Toshiba TCD2919BFG CCD Image Sensor: 10680-Pixel Linear Scanning, High-Resolution Applications and OEM Sourcing

High-resolution optical scanning places demanding requirements on the semiconductor detector at the centre of an imaging system. Equipment manufacturers developing precision document scanners, detailed print acquisition systems and specialized optical inspection instruments must capture small image features while maintaining accurate tonal information, stable electronic readout and consistent mechanical alignment. The difficulty is not simply obtaining a detector with a large number of sensing elements. Those elements must be matched to an optical system capable of resolving the intended detail, a scanning mechanism that moves accurately and electronics that preserve the information acquired by the semiconductor. Toshiba TCD2919BFG is a high-resolution CCD linear image sensor developed around these requirements, offering 10,680 sensing elements across four lines with both colour and monochrome acquisition capabilities. Its architecture is particularly relevant to equipment where fine spatial sampling is required across a defined optical field and where the design can accommodate the acquisition and processing conditions associated with a large linear detector.

Toshiba identifies colour scanners and laser printers as the principal application areas for Toshiba TCD2919BFG. The device is designed for lens-reduction imaging and supports approximately 1200 dpi optical sampling across A4-sized documents under the intended scanning arrangement. Its 10,680-element sensing rows use a 2.625 µm pitch and an 8.4 µm photosensitive height, providing a distinctive combination of fine sampling along the detector and a comparatively elongated sensing geometry. This arrangement should not be confused with a conventional area image sensor or with a high-speed industrial detector chosen primarily to maximize production throughput. The semiconductor is designed to obtain detailed line information that can be reconstructed into an image as the document or optical assembly moves through the scanning process.

The device also supports both red, green and blue acquisition and a separate black-and-white sensing arrangement. This four-line architecture is important because the required operating conditions and electronic processing differ according to the image information being collected. A machine acquiring monochrome intensity information can place different demands on the device than one reconstructing a full-colour image from three spatially separated sensing rows. Toshiba identifies a maximum line rate of approximately 6.1 kHz in monochrome mode and 3.2 kHz in colour mode, demonstrating that the higher element count must be considered together with the available acquisition speed. An OEM developing equipment around the device should therefore determine whether its application requires the maximum possible spatial detail, the available colour information or a particular balance between resolution and scanning time.

For manufacturers evaluating a CCD image sensor, Toshiba TCD2919BFG provides an example of why the complete technical specification matters more than a general resolution description. Two detectors may both be described as high-resolution linear CCD devices while differing substantially in pixel geometry, active sensing length, acquisition modes, electrical interface and physical package. The suitability of Toshiba TCD2919BFG depends on whether these particular characteristics match the equipment. A scanner designed to reproduce small printed characters across an A4 page may benefit from its dense sensing-element arrangement, while a machine inspecting fast-moving materials may encounter limitations arising from its available line rates. The correct purchasing decision follows an analysis of the actual optical and mechanical requirements rather than an assumption that the highest sensing-element count is automatically preferable.

Toshiba also incorporates high- and low-gain operating capabilities into the device, alongside high-sensitivity, low-dark-current photodiodes and an internal clamp circuit. These characteristics are relevant to image acquisition because document surfaces can contain very different brightness levels, ranging from dark printed features to pale backgrounds and photographic content. The available gain arrangements provide the camera designer with additional flexibility, but their use must be understood through Toshiba's specified operating modes and timing requirements. Increasing electronic gain does not create missing optical information and may influence noise behavior, so the gain configuration should be selected according to measured image quality within the finished equipment.

Kyptec Automation® provides a dedicated Image Sensor sourcing offering covering Toshiba alongside Hamamatsu and ON Semiconductor technologies. Its published category accepts manufacturer, part-number and quantity enquiries, providing a practical contact point for OEM manufacturers seeking an identified semiconductor rather than an unspecified imaging product. For equipment developers using Toshiba TCD2919BFG, this focused sourcing approach is useful because the sensor's four-line geometry, electronic timing and package requirements are integral to the approved scanner design. A substitute with a different sensing arrangement may require changes to optics, PCB construction or processing electronics, even if its advertised resolution appears similar. The exact manufacturer component should therefore remain identifiable throughout engineering evaluation and commercial purchasing.

This guide examines Toshiba TCD2919BFG as an individual high-resolution semiconductor, concentrating on its 10,680-element architecture, 1200 dpi A4 imaging capability, high- and low-gain arrangements, colour and monochrome operation, practical application limits and OEM sourcing considerations. It also explains how equipment designers can calculate useful object-space sampling, evaluate optical and electronic compatibility, and distinguish the manufacturer's intended scanner applications from possible specialized industrial inspection uses that require independent qualification. The objective is to provide a practical engineering and purchasing reference for selecting the correct device without overstating its performance or assuming that nominal resolution alone determines the quality of an industrial imaging system.

Toshiba TCD2919BFG Technical Architecture, 10680-Element Sampling and High-Resolution Image Acquisition

Toshiba TCD2919BFG contains four linear photodiode arrays, each with 10,680 effective sensing elements. Three of these arrays provide red, green and blue information, while the additional array supports black-and-white acquisition. The semiconductor is therefore capable of operating in different imaging arrangements, but the four sensing rows should not be interpreted as a conventional two-dimensional array containing 42,720 independently positioned image pixels. Each row samples an optical image along one direction, and the second spatial dimension is obtained through successive acquisitions as the inspected document or optical assembly moves. The detector's geometry must be coordinated with that movement if the resulting image is to preserve the correct proportions of printed features. An OEM should understand this distinction before selecting the camera electronics because the amount of image data, the required readout arrangement and the processing method all depend on how the lines are acquired and reconstructed.

The most distinctive geometrical feature of Toshiba TCD2919BFG is its 2.625 µm element pitch. Multiplying this pitch by 10,680 elements gives an active sensing length of approximately 28.035 mm, which Toshiba rounds to about 28.04 mm in its product comparisons. This relatively compact sensing length contains a large number of sampling positions, allowing an optical system to project a defined document width onto the detector while preserving fine nominal spatial sampling. For an A4 document width of approximately 210 mm, the relationship between the paper and sensor length produces an optical reduction of roughly 7.5 times. This is consistent with the manufacturer's intended A4 scanning configuration, although the final design must account for active imaging margins, optical reference dimensions and the practical field of view. The sensor should be selected according to the complete imaging geometry rather than a simple calculation based on pixel count.

For buyers researching linear CCD image sensors, the 10,680-element arrangement offers a clear technical distinction from devices with fewer sampling positions over similar or larger active lengths. A detector with finer pitch can represent more optical samples across a given projected image, potentially supporting improved detail acquisition where the lens can resolve the corresponding features. However, a smaller element pitch may place greater demands on optical sharpness, alignment and signal quality. If the lens produces blur extending across several sensing elements, the nominal advantage of finer sampling can be reduced substantially. An OEM should therefore evaluate the actual optical image formed at the semiconductor plane, particularly toward the edges of the active row where lens performance may differ from the centre.

Toshiba identifies an element height of 8.4 µm, providing a photosensitive dimension greater than the 2.625 µm pitch along the scanning row. This geometry influences how light is collected within the optical acquisition arrangement, but it should not be interpreted as additional independent spatial resolution perpendicular to the sensing line. The longitudinal resolution of a reconstructed scan is determined by successive acquisitions and mechanical movement. A longer photosensitive dimension may influence the collected optical signal and the effective integration of image information across the projected line, making it important to design the optics and scanning motion according to the actual detector geometry. The camera developer should evaluate the device's signal characteristics under the intended illumination rather than assume that finer horizontal sampling automatically provides greater sensitivity or better images in every condition.

Toshiba specifies the device for approximately 1200 dpi scanning across A4 paper, which can be understood through the relationship between sensing-element count and document width. Dividing 10,680 elements by 210 mm gives approximately 50.9 samples per millimetre before accounting for practical margins, while 1200 dpi corresponds to roughly 47.2 samples per millimetre. The available sensing-element count therefore provides a technical basis for the manufacturer's 1200 dpi application. Nevertheless, the resolution of the finished scanner is affected by lens sharpness, mechanical movement, illumination and electronic processing. A digital file labelled as 1200 dpi does not necessarily contain 1200 dpi of genuine optical detail if the scanner fails to resolve the corresponding document features. OEM qualification should therefore use appropriate test patterns and actual printed material rather than rely solely on output file settings or the semiconductor's nominal element count.

The four-line colour and monochrome architecture introduces important registration requirements. Toshiba identifies the separation between the red and green lines and between the green and blue lines as 31.5 µm, while the separation between the blue and black-and-white lines is 63 µm. These dimensions establish the physical relationship among the sensing rows and must be accounted for when the camera reconstructs information from a moving document. Because the lines occupy different positions, they observe the same printed feature at different moments. The required alignment in the final image depends on the sensor's physical geometry, the optical reduction and the movement of the scanning mechanism. If the processing system applies incorrect delays or movement compensation, small text may develop coloured fringes or monochrome information may become displaced relative to colour measurements.

Accurate registration is particularly important in high-resolution imaging because errors that are relatively small in physical dimensions can become visible across fine printed features. A document containing narrow black text, small coloured annotations or closely spaced lines provides a demanding test of the scanner's registration method. The processing system should associate measurements from the relevant sensing rows with the same physical document location rather than simply combine data acquired at the same instant. Changes in mechanical scan speed can complicate this process if the system assumes constant movement. An OEM should therefore design appropriate synchronization and verify registration using representative documents at the intended operating speeds. The sensor's high element count offers useful detail only when the reconstructed image preserves the correct relationship among the measurements.

The difference between colour and monochrome operating rates is another major selection consideration. Toshiba lists a maximum line rate of approximately 6.1 kHz for black-and-white operation and 3.2 kHz for colour operation. These values indicate different acquisition capabilities under the specified modes and should not be treated as interchangeable. A scanner obtaining colour information from three lines may require more time to acquire and transfer the necessary measurements than a configuration using monochrome acquisition. The exact performance depends on the manufacturer's timing requirements and the completed electronic system. An OEM should calculate the line acquisition rate needed for the desired scanning speed before deciding whether the device supports the intended equipment throughput.

The device's output data rates also differ according to acquisition mode. Toshiba identifies a maximum monochrome data rate of 70 MHz and a maximum colour data rate of 35 MHz. These figures describe aspects of the semiconductor's electronic output rather than the number of complete scanned lines per second. The processing electronics must be designed to capture the corresponding outputs accurately and maintain signal integrity under the intended operating configuration. High-resolution acquisition can produce substantial data even at moderate line rates, particularly when the scanner reconstructs several colour channels across a complete page. The camera or scanner controller must therefore provide sufficient electronic throughput and processing capability so that image data is not lost or corrupted during continuous operation.

The high- and low-gain capability provides another distinctive feature of Toshiba TCD2919BFG. Toshiba identifies these operating arrangements within the device's specifications, giving designers a way to select an appropriate signal response for the intended imaging conditions. Different document regions can produce very different optical signal levels, particularly where bright paper backgrounds coexist with dark graphics or low-reflectance printed areas. The available gain modes can support appropriate system design, but they must be evaluated together with the sensor's noise characteristics and the illumination reaching the detector. A higher output gain does not necessarily improve the usable information in every situation, especially if the optical signal is weak relative to the underlying noise. The OEM should choose the relevant gain configuration through representative image testing and consult the manufacturer's timing information for correct implementation.

Toshiba's product information identifies typical sensitivity values of 36.8 V/(lx·s) for the monochrome arrangement, with corresponding values of 12.2, 13.4 and 7.9 V/(lx·s) for red, green and blue respectively. These differences demonstrate that separate channels do not necessarily produce identical raw outputs under the same illumination. A colour scanner should therefore use suitable channel calibration and controlled lighting to reproduce document appearance consistently. The scanner's processing system may apply gain correction or other colour adjustments, but excessive correction cannot replace optical signal that was not acquired adequately. Engineering qualification should examine whether the selected illumination provides sufficient information across all three channels, including on dark or low-contrast document regions.

The electrical interface combines CMOS-level 3.3 V input clock drive requirements with a typical 10 V supply. Toshiba identifies a two-phase CCD clocking arrangement and an internal clamp circuit, both of which influence PCB design and output signal acquisition. The input drive levels should not be confused with the primary supply requirement, because the semiconductor uses different electrical functions that must be implemented according to its specifications. A scanner controller developed for another image sensor may not be directly compatible even if some of its digital signals operate at 3.3 V. The engineering team should review the complete electrical and timing requirements, design suitable supply regulation and verify the readout behavior with the intended acquisition hardware before approving the component.

Mechanical integration also deserves attention because Toshiba TCD2919BFG uses a 22-pin ceramic leaded chip carrier with through-hole mounting. The package affects the PCB footprint, component positioning and optical alignment within the scanner. A high-resolution sensing row requires stable geometry relative to the lens and scanning mechanism, particularly because focus variations or small alignment errors can reduce usable detail across the active field. The manufacturer provides package information and design resources, but OEM engineers should verify the applicable dimensions and reference locations from the current documentation rather than infer them from a related Toshiba device. Correct mechanical placement is essential to obtaining the benefit of the fine sensing-element pitch.

High-Resolution A4 Scanning, Laser Printer Imaging and Precision Industrial Applications

Toshiba identifies colour scanners and laser printers as the principal application areas for Toshiba TCD2919BFG. These applications require optical acquisition of fine printed or document-related information, with the device's 10,680-element configuration supporting high spatial sampling across an A4-sized field. In a document scanner, the image is constructed by acquiring successive lines as a document or optical assembly moves under controlled conditions. The sensor records the optical measurements, but the quality of the completed scan depends on maintaining consistent illumination, accurate movement, suitable colour registration and appropriate signal processing. An OEM should therefore evaluate the device as part of a complete document acquisition system rather than treating its 1200 dpi capability as an isolated semiconductor property.

A high-resolution document scanner must reproduce different types of content reliably. Fine text creates demanding requirements for spatial sharpness and channel alignment, while photographs and shaded graphics require suitable tonal response. Coloured documents introduce additional demands on calibration because the sensor's RGB channels have different spectral responses and typical sensitivities. A scanner that produces clear black text may still reproduce coloured images poorly if the illumination or processing system is inadequately designed. Toshiba TCD2919BFG provides fine sampling positions and separate colour measurements, but the OEM must establish how those measurements are converted into useful digital colour information. Appropriate calibration should be developed using representative reference targets and verified across the intended operating conditions.

For companies comparing a high resolution image sensor for document applications, the 1200 dpi capability is relevant where the equipment must retain small printed details or support enlargement of acquired information. However, the processing workflow should be matched to genuine optical capture rather than depend on software interpolation. Enlarging a lower-resolution image does not restore missing fine detail, and aggressive sharpening may introduce artificial edges. The optical system must therefore be capable of resolving features at the scale represented by the sensing elements, while the scanning mechanism should maintain sufficiently fine and consistent longitudinal movement. The OEM should validate the completed scanner using suitable test targets that reveal both horizontal and vertical resolution limitations.

Laser printer imaging presents a related but distinct application context. The manufacturer identifies laser printers within the product's intended scope, and such equipment may require precise acquisition of optical information associated with its imaging process. The exact use of a linear CCD depends on the printer's architecture and should not be generalized across every printing system. A sensor used for internal optical measurement or scanning may require particular alignment and timing arrangements different from those of a standalone document scanner. An equipment manufacturer should therefore examine the relevant mechanical and electronic design requirements before selecting Toshiba TCD2919BFG. The manufacturer's application designation provides a credible engineering starting point but does not establish compatibility with all printer models or operating methods.

Specialized inspection of fine printed material is another possible area for evaluation. A manufacturer may need to examine security printing, small registration marks, detailed labels or precision graphics under a controlled scanning arrangement. The high sensing-element count can provide useful cross-scan sampling when the optical field is matched appropriately, but the available line rate may limit how rapidly the material can move. A machine that transports documents at controlled speed can have a very different acquisition requirement from one inspecting high-speed packaging web. Before selecting the device, the OEM should calculate the required sampling in both directions and verify whether monochrome or colour acquisition satisfies the inspection criterion. The manufacturer's primary applications remain document and printer imaging, so industrial inspection suitability should be demonstrated independently.

Fine printed patterns can reveal the practical limits of optical resolution. Closely spaced lines may appear distinct in a digital representation only if the lens preserves their contrast at the detector plane. The smaller 2.625 µm element pitch allows more samples across a given semiconductor length, but it also places greater emphasis on optical performance and alignment. The camera should be tested with patterns spanning the full inspection width, because image sharpness and distortion may vary toward the ends of the optical field. A high-resolution sensor can record detailed variations faithfully only when those variations reach the photosensitive elements with sufficient contrast. This is especially important when the equipment must identify small defects that are near the limit of its optical sampling capability.

For OEMs evaluating a CCD linear sensor for precise edge measurement, monochrome acquisition may be useful where the relevant information is based on intensity transitions. The device's 10,680-element sensing row provides a fine set of nominal sampling positions, and the higher published monochrome line rate may be relevant if the target moves during acquisition. However, measurement accuracy depends on optical magnification, calibration, signal quality and the algorithm used to estimate edge position. An image sensor with a 2.625 µm pitch does not automatically provide 2.625 µm measurement accuracy on the inspected object, because the object-space scale differs according to the lens. The system must be calibrated using appropriate reference features before reported dimensions can be treated as reliable measurements.

Colour-sensitive inspection may be necessary when a defect involves a printed shade, pigment variation or incorrect colour element rather than a geometric difference. Toshiba TCD2919BFG offers RGB acquisition, allowing a suitably designed system to compare spectral responses across relevant printed regions. However, the three colour lines are physically separated and must be registered correctly as the document or material moves. The lower published colour-mode line rate also affects the permissible relationship between transport speed and sampling density. A manufacturer should not choose colour acquisition automatically merely because it appears to provide more information. The useful question is whether the additional colour measurements improve the system's ability to distinguish acceptable and defective material under realistic conditions.

The four-line architecture also creates opportunities for engineering evaluation where a scanner needs a monochrome measurement in addition to colour-related information. However, the OEM must determine which operating arrangements are supported by the manufacturer's documentation and whether the additional information is available under the intended timing conditions. It would be inappropriate to assume that the highest monochrome line rate applies simultaneously to all RGB channels or that colour and black-and-white measurements can always be combined without registration compensation. The scanner's processing architecture should be designed around a clearly defined acquisition mode, with alternative modes validated separately where needed. This prevents performance claims based on mixing specifications from different configurations.

Illumination is particularly important in high-resolution scanning because the camera must preserve useful contrast across small features. A bright paper background and dark printed mark may produce a relatively strong signal difference, while pale graphics or subtle surface variations can be more difficult to represent. The device's high- and low-gain capabilities may help designers select appropriate electronic operating conditions, but gain settings should be evaluated together with noise, exposure and channel response. Increasing light intensity can improve signal in some circumstances, but excessive illumination may cause saturation or introduce reflections on glossy material. The OEM should test representative documents under controlled lighting and determine whether the resulting signal supports the intended recognition or reproduction requirements.

Industrial operating conditions may also affect the suitability of the device. A high-resolution scanner installed inside specialized manufacturing equipment can experience temperature variation, vibration and optical contamination that are less severe in controlled office environments. The camera housing should maintain optical alignment and protect the detector, while the electronics should operate within Toshiba's specified electrical and environmental limits. A scanner that performs well during initial laboratory evaluation may require additional engineering work to maintain the same performance during sustained industrial operation. OEM manufacturers should therefore qualify the complete assembly according to actual usage conditions rather than rely exclusively on the semiconductor's intended application category.

For purchasing teams researching industrial image sensor options, the main decision should remain whether Toshiba TCD2919BFG has already been validated for the intended equipment. Kyptec Automation® offers a dedicated Image Sensor enquiry channel for identified Toshiba products, allowing manufacturers to submit the required part number and quantity for sourcing consideration. This is useful when the semiconductor has become part of an approved scanner design whose mechanical and electronic architecture depends on its specific characteristics. For a new industrial application, the engineering team should first establish technical suitability before committing to recurring quantities. Accurate qualification and procurement are complementary activities, but one should not substitute for the other.

Toshiba TCD2919BFG OEM Integration, Purchasing Verification and Global Component Sourcing

Once Toshiba TCD2919BFG has been selected for an equipment design, the OEM should preserve its precise manufacturer identity across engineering records, purchasing enquiries and production documentation. This is particularly important because Toshiba's linear CCD range includes other products with different sensing-element counts, pixel geometries and readout arrangements. A general purchasing request for a high-resolution Toshiba CCD may lead to confusion if the supplier identifies another product that appears similar at a catalogue level. The approved scanner may depend on the specific 28.04 mm sensing length, four-line array geometry, input drive requirements and package of Toshiba TCD2919BFG. An alternative component should therefore be reviewed by engineering rather than accepted automatically on the basis of similar nominal resolution.

For manufacturers seeking a Toshiba image sensor supplier, Kyptec Automation® provides a dedicated Image Sensor sourcing channel covering Toshiba together with Hamamatsu and ON Semiconductor technologies. Its published enquiry process asks customers to provide the make, part number and quantity, which supports focused discussion of a specific semiconductor requirement. This is particularly useful for OEM scanner manufacturers and industrial equipment developers because component identity must remain consistent from prototype qualification through recurring manufacturing. Actual availability, commercial pricing, lead time and shipment conditions should be confirmed for the particular order. The existence of a manufacturer datasheet or a sourcing category does not guarantee that every device is available immediately in the requested quantity.

Toshiba's current product information also notes that representative semiconductor family designations may require additional characters to form the complete commercial ordering code. An OEM should therefore verify the exact configuration associated with the offered part before issuing a purchase order. The quotation should identify the product sufficiently clearly for engineering and purchasing personnel to determine whether it corresponds to the approved semiconductor. Where a supplier offers a variant with different ordering characters, the significance of those differences should be established rather than assumed unimportant. This reduces the risk of obtaining a device with a different package or commercial configuration from the one used during camera development.

Engineering qualification should examine the optical, electrical and mechanical performance of the actual sensor within a representative scanner. The device should be operated with the intended clocking arrangement, typical supply conditions and acquisition electronics, while its outputs should be evaluated using test documents or patterns appropriate to the application. If the scanner operates in colour mode, the tests should include RGB registration, channel balance and fine printed features. If monochrome operation is used, the tests should verify signal quality and acquisition performance at the required scanning speed. The objective is to establish that the complete equipment meets its intended performance requirements rather than merely confirm that the semiconductor generates an output.

The electrical design should respect Toshiba's specified 3.3 V input clock levels and typical 10 V supply requirement. These characteristics are not interchangeable with the requirements of every other Toshiba CCD or CMOS detector, so the camera PCB must be developed from the applicable manufacturer documentation. The output chain should support the relevant data rate and preserve signal integrity, particularly where the high sensing-element count creates substantial information flow during continuous scanning. Power stability and timing accuracy should be verified because electronic disturbances can affect image consistency and the reproduction of small details. The internal clamp circuit assists with aspects of readout design, but it does not replace complete electronic engineering.

Mechanical integration must account for the 22-pin CLCC package and the optical alignment of the detector's active sensing lines. The OEM should use the manufacturer's package drawing and approved footprint information when designing the PCB and camera housing. Toshiba provides references to electronic CAD resources but also cautions that automatically generated footprints may differ from its reference dimensions, making independent verification important. A sensor positioned incorrectly relative to the lens can reduce sharpness or introduce registration problems, particularly in a scanner developed for high-resolution A4 acquisition. Appropriate handling and contamination precautions should also be incorporated into production procedures because optical semiconductor surfaces and packages require controlled assembly conditions.

For organizations intending to buy image sensors in recurring quantities, the purchasing plan should follow the manufacturing schedule and the exact component approved by engineering. A scanner manufacturer may use one Toshiba TCD2919BFG in each assembly, but the total quantity required depends on expected production, assembly yield and justified service inventory. The purchasing team should confirm the commercial conditions associated with its forecast rather than assume that a large anticipated requirement guarantees reserved supply. Availability and lead time can vary according to the requested product and ordering configuration. Maintaining accurate component records allows production teams to distinguish the approved semiconductor from other devices that share a broad CCD description.

International sourcing adds considerations involving shipment destination, documentation and applicable transaction terms. Kyptec Automation® publishes worldwide export enquiry information and provides contact details through its Image Sensor category. An OEM located outside India can communicate its requirement for Toshiba TCD2919BFG together with the quantity and delivery destination for commercial consideration. Actual availability, shipment arrangements and relevant costs must be established before the order is incorporated into the manufacturing schedule. Import duties, taxes and receiving procedures may affect total landed cost depending on the destination and agreed terms. A purchasing comparison should therefore reflect the complete transaction rather than the semiconductor unit price alone.

Product lifecycle and continuing availability should also be considered when a scanner is expected to remain in production for an extended period. Toshiba provides current documentation for Toshiba TCD2919BFG, including an English datasheet dated May 2026, but the presence of product information does not establish unlimited future supply. Buyers should verify the relevant ordering conditions and available lifecycle information when planning long-term purchases. If a replacement is proposed, engineering should compare the sensing geometry, package, electrical drive and acquisition capabilities before authorizing any change. A newer or more readily available detector may offer different technical features without providing direct compatibility with an established scanner.

Kyptec Automation® provides a useful point of contact for OEM buyers seeking defined image sensor components through its dedicated category. The enquiry process allows manufacturers to communicate Toshiba TCD2919BFG by name, together with the required quantity, while clarifying the commercial details of the requested sourcing transaction. Its manufacturer-focused offering is relevant because specialized CCD devices are not generic interchangeable components. By preserving accurate part-number information and keeping engineering qualification connected to purchasing, OEM manufacturers can reduce avoidable supply misunderstandings and maintain consistency across scanner production.

Frequently Asked Questions About Toshiba TCD2919BFG CCD Image Sensor

1. Is Toshiba TCD2919BFG a monochrome-only CCD sensor or a combined colour and black-and-white device?

Toshiba TCD2919BFG supports both RGB colour and black-and-white acquisition through a four-line CCD architecture. The device contains three colour-sensitive rows together with a separate monochrome sensing row, each providing 10,680 effective sensing elements. This arrangement distinguishes it from a conventional single-line monochrome detector and from an ordinary three-line RGB sensor without a separate black-and-white array. The available acquisition speed and electronic configuration differ according to the selected mode, making it important for the OEM to specify how the sensor will operate within the finished equipment. Toshiba identifies maximum line rates of approximately 6.1 kHz in monochrome mode and 3.2 kHz in colour mode, so the faster figure should not be applied indiscriminately to colour acquisition. The engineering team should consult the relevant timing specifications and validate each intended operating configuration before approving the component for manufacturing.

2. Why does Toshiba TCD2919BFG use 10,680 sensing elements for A4 document scanning?

The 10,680-element arrangement allows a fine sampling interval across an A4 document when the optical system projects the page width onto the detector's approximately 28.04 mm active sensing line. Toshiba identifies the device with approximately 1200 dpi scanning, reflecting the relationship between document width, optical magnification and available sensing positions. The semiconductor provides a high number of samples across the page, which can be useful for reproducing small characters, detailed graphics and fine printed patterns. However, the number of elements does not independently guarantee that the completed scanner resolves all corresponding detail. The lens must form a sufficiently sharp image, illumination must provide adequate contrast and the scanning mechanism must acquire successive lines at an appropriate interval. A properly designed scanner can use the detector's capabilities effectively, while poor optical or mechanical integration may reduce actual image detail despite the high nominal resolution.

3. What is the practical significance of the 2.625 µm pixel pitch in Toshiba TCD2919BFG?

The 2.625 µm pitch defines the nominal spacing between neighbouring sensing elements along the detector row and contributes to the device's high sampling density. With 10,680 elements, it produces an active sensing length of approximately 28.04 mm, allowing a relatively compact optical image to be sampled at many positions. The smaller pitch can support fine-detail acquisition when the lens resolves the corresponding spatial information, but it also places demands on optical sharpness, focus and alignment. An OEM should not assume that features smaller than the nominal pitch can always be measured accurately or that object-space resolution equals the physical semiconductor element size. The lens magnification determines how much real-world distance corresponds to each detector element, while calibration and image quality influence the final measurement. The device should therefore be evaluated using realistic optical targets rather than selected solely because its pixel pitch appears numerically small.

4. How does the 8.4 µm sensing-element height affect imaging performance?

The 8.4 µm element height describes the photosensitive dimension perpendicular to the 2.625 µm sampling pitch along the sensing row. This elongated geometry influences how the optical image is collected, but it does not provide additional independently resolved pixels in the scanning direction. In a linear imaging system, the second spatial dimension is obtained by acquiring successive lines as the document or optical assembly moves. The element height may affect the optical signal collected from the projected line and should be considered when designing focus and illumination conditions. However, the usable signal also depends on detector response, exposure, lens transmission and the properties of the scanned material. An OEM should avoid interpreting the element's physical dimensions as a direct measurement-accuracy specification. The appropriate way to evaluate performance is to test the complete optical and electronic system with representative fine-detail targets under the intended acquisition conditions.

5. What is the difference between high-gain and low-gain operation in Toshiba TCD2919BFG?

Toshiba identifies high- and low-gain capabilities among the device's features, giving the scanner designer different electronic response options for the acquired CCD signal. These modes can be relevant when the application includes documents or optical targets producing different intensity ranges, but the correct setting depends on the manufacturer's specified operating arrangement and the signal quality required by the equipment. A higher gain may increase the output associated with a given collected signal, yet it does not increase the underlying amount of light reaching the detector or remove the effects of sensor and electronic noise. A low-gain arrangement may be appropriate under different illumination conditions where sufficient signal is available. The OEM should examine output levels, noise, tonal reproduction and saturation across representative documents before selecting a gain configuration. The decision should follow measured scanner performance rather than a general assumption that one gain mode is always superior.

6. Why is the maximum monochrome line rate higher than the colour line rate?

Toshiba TCD2919BFG uses different readout arrangements for monochrome and colour acquisition, and the manufacturer publishes different maximum line rates for those modes. The monochrome comparison identifies approximately 6.1 kHz, while colour operation is listed at around 3.2 kHz. The distinction reflects the amount of information and electronic configuration associated with the selected acquisition mode. A document scanner operating in black-and-white mode may therefore have a different potential acquisition schedule from one collecting complete RGB information. However, the finished scanner's speed also depends on movement, illumination and processing requirements. A higher line rate is only useful when the sensor receives enough optical signal and the system maintains correct spatial sampling. OEM manufacturers should calculate the required acquisition frequency from the intended scanning resolution and mechanical speed, then verify that the selected mode produces acceptable image quality under the actual operating conditions.

7. Can Toshiba TCD2919BFG be used for precision inspection of fine printed patterns?

The device may be evaluated for inspection of fine printed patterns where the application requires high cross-scan sampling and can accommodate the available acquisition rate. Its 10,680 elements provide many discrete measurements across the projected field, which can be useful for examining small printed features, registration references or detailed graphics. Nevertheless, Toshiba identifies colour scanners and laser printers as the primary application areas, so use in a particular industrial inspection machine requires separate engineering qualification. The optical system must resolve the relevant feature size, while the movement and electronic acquisition must preserve the required longitudinal information. If colour differences determine the inspection result, the lower colour-mode line rate and registration requirements must be considered. A manufacturer should test actual acceptable and defective material rather than assume that the semiconductor's high pixel count guarantees recognition of fine defects in every printing process.

8. How important is RGB line registration when scanning fine text at 1200 dpi?

RGB registration is particularly important at high spatial sampling because small misalignments between colour measurements can become visible around narrow printed boundaries. Toshiba TCD2919BFG uses physically separated red, green and blue sensing arrays, with Toshiba identifying 31.5 µm between adjacent colour arrays. As the document or optical assembly moves, each line observes the same feature at a different moment. The processing system must compensate for that movement so the corresponding measurements are assigned to the correct image position. If registration is inaccurate, black text can show coloured edges, and fine graphics can lose clarity even when the individual sensing lines acquire valid signals. The OEM should calibrate the scanning mechanism and line reconstruction using high-contrast reference targets, then confirm that alignment remains consistent at the intended scan speeds. Correct colour registration is essential to obtaining the practical benefit of the device's fine sensing-element pitch.

9. What should an OEM consider when selecting optics for the 28.04 mm active sensing length?

The optical system must project the required document or inspection width onto the detector's approximately 28.04 mm active sensing line while maintaining sufficient sharpness across the entire field. A4 scanning requires an appropriate reduction ratio, but the actual design must consider margins, mechanical geometry and the manufacturer's reference dimensions. The high sensing-element count places demanding requirements on lens resolution because small projected details must remain distinguishable at the detector plane. Focus variation, optical distortion and insufficient illumination toward the edges can reduce the usefulness of the available sampling positions. A scanner intended for precision measurement may also require calibration of geometric distortion so that the position of features can be interpreted accurately. The OEM should therefore select the optical arrangement based on the actual task and confirm performance using representative targets across the full field. A lens that merely covers the detector is not necessarily capable of supporting genuine high-resolution acquisition.

10. Can Toshiba TCD2919BFG inspect moving products on an industrial conveyor?

The device can be evaluated for a controlled moving-object scanning arrangement, but its suitability depends on the required inspection width, object speed, feature size and selected operating mode. Toshiba primarily identifies document scanning and laser-printer applications, which often operate under controlled scanning geometry. A conveyor inspection system may require a substantially different acquisition schedule, especially if material moves rapidly or cannot be presented consistently. The OEM should calculate the necessary line rate from conveyor velocity and the desired longitudinal sampling interval, then compare that requirement with the manufacturer's specifications for monochrome or colour operation. The optical system and illumination must also provide enough useful signal during the available integration period. If a very high throughput is required, the device's line-rate limits may make another detector more appropriate. Any industrial conveyor application should therefore undergo independent system-level testing before production approval.

11. How do the 70 MHz monochrome and 35 MHz colour data rates influence electronics design?

The published maximum data rates describe electronic output capabilities associated with the relevant operating modes rather than complete scanned images per second. The camera controller must capture the sensor outputs according to Toshiba's specified timing while maintaining suitable signal integrity and processing throughput. With 10,680 effective elements per line, even a moderate line frequency can generate substantial acquired information, especially during RGB scanning. The analog acquisition chain, clock generation and downstream processing should therefore be selected according to the intended mode and operating conditions. Incorrect timing or inadequate electronic throughput can affect reconstructed image quality despite the detector's fine sampling capability. The OEM should also verify the supply architecture, grounding and calibration behavior within the completed scanner. Data-rate specifications are important engineering limits, but they should be evaluated together with line acquisition, exposure and document movement rather than treated as standalone evidence of scanner speed.

12. Does Toshiba TCD2919BFG require both 3.3 V and 10 V electrical arrangements?

Toshiba identifies CMOS-level 3.3 V input clock drive requirements together with a typical 10 V supply for Toshiba TCD2919BFG. These figures apply to different parts of the semiconductor's electrical interface and should not be interpreted as one interchangeable operating voltage. The engineering team must design the appropriate clocking, control and power circuitry according to the manufacturer's specified conditions. A scanner PCB developed for another linear CCD may not support the device without modification, even if it already contains 3.3 V digital electronics. Incorrect drive levels or supply arrangements can affect performance and may damage the semiconductor if specified limits are exceeded. The OEM should review the complete manufacturer timing and electrical documentation before releasing a production PCB. Suitable voltage regulation, grounding and signal acquisition are necessary to support dependable operation at the intended scanning settings.

13. Can Toshiba TCD2919BFG directly replace another 10,680-element CCD image sensor?

A matching element count does not establish that two CCD devices are mechanically, optically or electrically interchangeable. Toshiba TCD2919BFG has a particular 2.625 µm pitch, four-line colour and monochrome architecture, gain arrangement, clocking requirement and 22-pin ceramic package. Another sensor with 10,680 elements may differ in one or more of these characteristics, requiring changes to the optical magnification, PCB, signal processing or mechanical mounting. Even a related Toshiba product should be evaluated using its complete datasheet before being approved as a replacement. An existing scanner may depend on specific colour-line separation and calibration settings that cannot be transferred directly to another device. The purchasing department should therefore preserve the engineering-approved manufacturer ordering designation and request that exact semiconductor unless a substitute has completed suitable qualification. Kyptec Automation® provides an enquiry route for accurately identified Toshiba component requirements.

14. What should buyers verify about the complete ordering code and lifecycle before placing an OEM order?

The buyer should confirm the complete manufacturer ordering designation applicable to the requested device, including any additional commercial characters required for the supplied configuration. Toshiba notes that representative part numbers displayed on its website may correspond to product families and that additional characters can appear in delivered product codes. The purchasing team should therefore verify the exact component described in a quotation rather than assume that a shortened model name identifies every relevant detail. Current availability, quantity, lifecycle information and delivery conditions should also be checked before committing to a manufacturing schedule. Toshiba publishes recent technical documentation for Toshiba TCD2919BFG, but the presence of an updated datasheet does not guarantee immediate stock or unrestricted future supply. An OEM expecting several years of scanner production should connect purchasing plans to the approved component and review commercial conditions periodically. Kyptec Automation® can receive the specified make, part number and quantity for sourcing consideration.

15. Can international equipment manufacturers enquire about Toshiba TCD2919BFG through Kyptec Automation®?

Kyptec Automation® publishes a dedicated Image Sensor offering covering Toshiba, Hamamatsu and ON Semiconductor technologies and provides contact information for worldwide export enquiries. An international manufacturer seeking Toshiba TCD2919BFG can identify the required make, complete part number, quantity and delivery destination, allowing the enquiry to focus on the exact semiconductor needed for its equipment. This is relevant to scanner and industrial imaging OEMs because the component's four-line architecture, package and electronic interface should correspond to the engineering-approved design. Actual availability, pricing, shipment arrangements and applicable documentation must be confirmed for the requested transaction rather than inferred from the public product category. Buyers should also consider import responsibilities and receiving procedures where relevant. The value of the dedicated enquiry channel is the ability to communicate a precise manufacturer-specific requirement for commercial consideration without substituting a general high-resolution image sensor description.

16. Why should OEM scanner manufacturers consider Kyptec Automation® for Toshiba TCD2919BFG sourcing?

Kyptec Automation® provides a dedicated Image Sensor sourcing offering that covers Toshiba semiconductor devices and accepts enquiries based on the make, exact part number and required quantity. This approach is useful for OEM scanner manufacturers because Toshiba TCD2919BFG is not a generic imaging component: its 10,680-element four-line architecture, gain capabilities, electrical drive requirements and mechanical package influence the complete equipment design. Once the device has been qualified, purchasing personnel should continue to request the same approved semiconductor unless engineering authorizes a suitable alternative. Kyptec Automation® offers a focused channel for communicating that requirement, including enquiries from manufacturers outside India. The company's Image Sensor portfolio also covers other established semiconductor manufacturers, but those products should not be treated as directly interchangeable with Toshiba TCD2919BFG. Commercial availability, pricing and delivery arrangements must be confirmed for each request, while technical suitability remains dependent on the OEM's engineering qualification.

Conclusion: Toshiba TCD2919BFG for High-Resolution Linear Imaging and OEM Sensor Procurement

Toshiba TCD2919BFG is a high-resolution CCD linear image sensor developed for applications requiring fine optical acquisition across a controlled scanning field. Its 10,680 sensing elements per line, 2.625 µm pitch and approximately 28.04 mm sensing-row length provide a technical basis for the manufacturer's intended 1200 dpi A4 imaging capability. The device also combines three RGB sensing lines with an additional monochrome arrangement, creating different acquisition possibilities within one semiconductor architecture. These features make it relevant to colour document scanners, laser-printer imaging systems and specialized scanning equipment that can be engineered around its optical and electronic characteristics. However, nominal resolution does not independently guarantee fine-detail reproduction or industrial defect detection, because the completed system must also provide appropriate optics, illumination, mechanical movement and processing.

The distinction between the device's operating modes is important to practical selection. Toshiba identifies different maximum line rates and data rates for monochrome and colour acquisition, meaning that equipment manufacturers must calculate the actual scanning requirements before selecting the intended mode. The high- and low-gain capabilities provide further electronic flexibility, but gain choices must be evaluated against signal quality and the illumination available at the sensor. Accurate colour registration is essential when reconstructing information from the physically separated RGB lines, particularly where the scanner must reproduce fine printed details. A reliable design should therefore be validated through representative optical testing and controlled acquisition rather than judged from individual datasheet figures alone.
