VSP3200Y - 16-Bit 8MSPS CCD Signal Processor | TI
MPN： VSP3200Y ✓ 啟用中VSP3200Y 概覽
A CCD/CIS analog front end is the mixed-signal stage between an image sensor and a digital image processor. It samples tiny charge-derived pixel voltages, removes reset and kTC noise through correlated double sampling (CDS), amplifies the signal to match the ADC input range, and digitizes it. Within the signal chain hierarchy, the AFE sits between the sensor and the image-signal processor, and is a critical determinant of final image dynamic range and noise floor.
Key features include an integrated triple correlated double sampler (CDS), a programmable gain amplifier with up to +13 dB gain, selectable operating modes (1-channel or 3-channel CCD mode at up to 8 MSPS), selectable normal or demultiplexed output modes, and an offset control range of +3V. The 16-bit conversion resolution preserves fine shadow detail in scanned images, essential for document and film scanners.
Architecturally, the VSP3200 combines three CDS/PGA channels feeding a 16-bit ADC pipeline optimized for line-rate scanning. The demultiplexed output mode makes the device interface compatible with the VSP3210, which is pin-to-pin compatible with the VSP3100 in that mode, providing a migration path to a one-chip solution.
Typical applications include flatbed document scanners, film scanners, CIS-based scanner modules, and industrial inspection cameras that use CCD or CIS sensors.
Design consideration: because the part runs from a single +5V rail, keep the analog 5V supply clean and well decoupled; noise on this rail directly appears in pixel data at 16-bit resolution levels.

典型應用
VSP3200Y 適用於 6 應用s: Flatbed Document Scanners, Film and Slide Scanners, CIS-Based Scanner Modules, Industrial Machine-Vision Inspection, Medical Document and Film Digitization, Legacy Scanner BOM Maintenance.
Flatbed Document Scanners
The VSP3200Y was designed specifically as a CCD signal processor for scanner applications, per the TI datasheet description. Its three integrated correlated double samplers remove reset noise from each pixel of a trilinear CCD array, while the +13 dB programmable gain amplifier adapts sensor output swing to the 16-bit ADC input range, preserving shadow detail in text and photographs. Operating at up to 8 MSPS in 3-channel mode, it supports the line rates of typical document scanners from a single +5V rail, simplifying the power tree of desktop scanner products. The selectable normal/demultiplexed output mode lets designers choose the data interface that best matches the scanner's image-processing ASIC.

Film and Slide Scanners
Film scanners demand the highest possible dynamic range because transparencies contain dense shadow regions. The VSP3200Y's 16-bit conversion resolution and CDS-based noise reduction deliver the low noise floor needed to distinguish detail in dense negatives. The programmable PGA gain allows the analog chain to be optimized per film density, and the +3V offset control range accommodates sensor black-level variation between exposures. Running from a single +5V supply keeps the compact mechanical envelope of film scanners simple. At 8 MSPS the device supports the pixel rates of 35 mm and medium-format scanning heads with margin.
推薦
CIS-Based Scanner Modules
Contact Image Sensor (CIS) modules, common in compact and portable scanners, output analog pixel signals that benefit from the same correlated double sampling and gain staging as CCD arrays. The VSP3200Y is specified for CCD/CMOS/CIS sensors, so it can condition CIS line data at up to 8 MSPS. Its 1-channel operating mode suits single-channel CIS configurations, reducing power and simplifying timing, while 3-channel mode serves color triplet CIS arrays. The 48-LQFP (7x7 mm) package fits within the thin mechanical profile of CIS modules, and the single +5V supply aligns with the voltage rails typically available inside scanner housings.

Industrial Machine-Vision Inspection
Industrial inspection cameras built around linear CCD sensors use the VSP3200Y to digitize product surfaces on production lines. The 16-bit resolution enables detection of subtle contrast variations in surfaces such as printed packaging, glass, and metal finishes, while the 8 MSPS maximum rate matches line-scan speeds of conveyor-based systems. Correlated double sampling suppresses kTC noise that would otherwise appear as fixed-pattern artifacts across scan lines. Operation from 0C to +85C covers typical factory-floor ambient conditions. The demultiplexed output mode provides parallel data delivery to FPGA-based image processing back ends.

Medical Document and Film Digitization
Digitizing radiographic film and patient documents in medical records departments requires high dynamic range and stable, repeatable capture. The VSP3200Y's 16-bit output and CDS noise reduction support the tonal depth needed for diagnostic-grade film scans, and its +13 dB PGA range handles the wide density span of medical film. The TI datasheet specifies operation across 0C to +85C, adequate for typical office and clinical environments. Because the device interfaces compatibly with the VSP3210 one-chip product, medical equipment makers can consolidate later-generation designs onto the VSP3210 without changing the mechanical platform or power architecture.

Legacy Scanner BOM Maintenance
Many installed scanner and copier platforms were designed around the VSP3200 family and continue to require sourcing of these mature parts. The VSP3200Y remains listed at DigiKey and LCSC as of 2026-09-14, providing continued production support. Where exact sourcing becomes difficult, the VSP3210Y offers a documented complete replacement per FindIC cross-reference data, with consistent terminals, package, and performance requiring no circuit modification. Maintaining the VSP3200/VSP3210 family in a qualified-alternates program protects long-life industrial and office-equipment products against allocation events.

主要差異化特點

- Integrated triple CDS + PGA reduces external component count (對比VSP3100Y)
- Upgrade path without board redesign (對比VSP3210Y)
設計說明
The VSP3200Y operates from a single +5V supply, and at 16-bit resolution the effective LSB size is roughly 45 uV referred to a 3V full-scale range. Supply ripple within the CDS/PGA passband translates directly into pixel-level artifacts. Use a dedicated low-noise 5V LDO (or a well-filtered output of the scanner 5V rail) with bulk 10 uF plus 0.1 uF ceramic decoupling placed at the supply pins, and keep the analog ground return separate from digital ground until a single star point.
CCD output nodes are high-impedance sources; route the sensor-to-CDS analog inputs as short, guarded traces away from the digital output bus. The 8 MSPS demultiplexed output switching can couple charge back into the analog front end, so limit series resistance on digital lines and consider small series damping resistors (22-33 ohm) to reduce ringing. Keep the offset-control node quiet since its +3V range sets effective black level.
Do not assume mode pin strapping is identical across the family: the VSP3210 is a one-chip product whose interface matches the VSP3200 only in demultiplexed output mode. When qualifying VSP3210Y as an alternate, re-verify timing and mode-select settings against the VSP3200/VSP3210 datasheet (Rev. B). Also confirm the operating mode selection (1-channel vs 3-channel) matches the sensor in use, since mis-set modes produce truncated or duplicated scan lines.
