VSP3200Y-2K - 16-Bit 8MSPS CCD Signal Processor | Texas Instruments
MPN： VSP3200Y-2K ✓ 啟用中VSP3200Y-2K 概覽
An analog front end for image sensors is the circuit block between the imaging array and the digital image processor. It performs correlated double sampling (CDS) to remove reset noise and kTC noise from the CCD output, applies programmable gain to normalize signal amplitude across color channels, and digitizes the conditioned signal with a high-resolution ADC. Within the system hierarchy, the AFE sits inside the imaging signal chain: image sensor -> AFE (CDS + PGA + ADC) -> DSP/ASIC -> host interface.
Key features of the VSP3200Y include three Correlated Double Samplers (CDSs) and three Programmable Gain Amplifiers (PGAs) that process CCD signals from 3-channel (RGB) scanners, a 16-bit conversion path running at up to 8 MSPS, dual output mode for flexible host interfacing, and single +5V operation that simplifies power tree design in desktop scanner platforms.
Technically, the VSP3200Y integrates the complete analog processing chain for CCD signal conditioning: the CDS stages sample the pixel signal twice to cancel low-frequency drift and reset noise, the PGAs allow per-channel gain calibration, and the internal 16-bit ADC delivers 8 Msps throughput. Interface compatibility with the VSP3210 single-chip product, which is itself pin-to-pin compatible with the VSP3100 in demultiplexed output mode, provides a migration path for higher integration designs.
Typical applications are flatbed and document scanners using CCD or CIS linear arrays, industrial inspection cameras, and desktop imaging peripherals that require 16-bit depth at moderate 8 MSPS speeds.
A key design consideration is layout of the analog ground and the CCD output trace: keep the sensor-to-CDS input path short, guard it from digital output drivers, and provide a clean +5V rail with local decoupling, because residual reset noise not removed by the CDS directly limits the effective 16-bit resolution.

典型應用
VSP3200Y-2K 適用於 6 應用s: Flatbed Document Scanners, CIS-Based Scanner Modules, Industrial Inspection Cameras, Medical Document and Film Digitizers, Color Proofing and Graphic Arts Scanners, Security and Biometric Capture Devices.
Flatbed Document Scanners
The VSP3200Y-2K fits flatbed and document scanners because its three CDS + PGA channels map directly onto the three RGB taps of a linear CCD array, and its 16-bit, 8 MSPS path delivers the dynamic range needed for 48-bit-per-pixel color capture. The correlated double samplers cancel reset noise at the CCD output before it can corrupt the least significant bits, while the programmable gain stages balance channel-to-channel sensitivity differences. Placed immediately after the CCD output amplifiers with a clean +5V rail and short analog traces, the AFE digitizes the conditioned signal internally, and the dual output mode streams data to the scanner ASIC. The single-supply operation simplifies the sensor head power design.

CIS-Based Scanner Modules
For contact image sensor (CIS) modules used in compact multifunction printers and portable scanners, the VSP3200Y-2K provides a 3-channel, 16-bit, 8 MSPS front end that conditions the lower-amplitude CIS outputs through its programmable gain amplifiers. Although CIS arrays produce less reset noise than CCDs, the CDS stages still remove kTC and offset errors, preserving the effective number of bits at the 16-bit ADC. The single +5V supply matches the power rails typically available inside CIS module housings, and the 48-pin LQFP footprint fits the narrow PCB real estate along the scan line. Gain calibration per channel compensates LED color variation, keeping inter-channel uniformity within acceptable limits across production units.
推薦
Industrial Inspection Cameras
Machine-vision inspection stations that use linear CCD arrays for web monitoring, print verification, and surface defect detection benefit from the VSP3200Y-2K's 16-bit depth at 8 MSPS, which resolves subtle density differences that 12- or 14-bit front ends miss. The three channels can process tri-linear color sensors or parallel taps of a monolithic line-scan CCD, and the correlated double samplers suppress the reset noise that dominates at low light levels typical of high-speed web inspection. The dual output mode interfaces cleanly to FPGA capture logic, and 0 C to +85 C operation covers factory-floor ambient conditions. Per-channel PGA calibration allows matching sensors swapped during maintenance without full system recalibration.

Medical Document and Film Digitizers
Digitizing radiographic film and high-density medical documents demands the 16-bit dynamic range that the VSP3200Y-2K delivers at 8 MSPS, sufficient to distinguish the full optical density range of X-ray films while scanning at practical line rates. The three CDS + PGA channels handle the RGB taps of the scanner's linear CCD, and the correlated double sampling architecture suppresses reset noise that would otherwise appear as banding artifacts in diagnostic images. The single +5V supply keeps the sensor head electronics simple, and the LQFP-48 package supports compact mechanical designs for desktop digitizers. Gain programmability allows per-model calibration to compensate for lamp and sensor aging over the equipment lifetime.

Color Proofing and Graphic Arts Scanners
Prepress color proofing scanners require exact tonal fidelity, and the VSP3200Y-2K addresses this with 16-bit conversion, 8 MSPS throughput for high line rates, and three independent CDS/PGA channels for R, G, and B taps. Correlated double sampling removes the reset noise floor that would otherwise limit shadow detail, a critical region for graphic arts reproduction, while per-channel programmable gain supports precise colorimetric calibration against IT8 targets. The dual output mode feeds host capture cards at the required 16-bit word width, and the 0 C to +85 C range suits studio environments. Its +5V single supply also simplifies retrofit into legacy proofing scanner chassis during electronics refurbishment.

Security and Biometric Capture Devices
Fingerprint and ID-document capture peripherals using linear CCD or CIS arrays use the VSP3200Y-2K to obtain the 16-bit grayscale depth needed for reliable minutiae extraction and document security feature verification at 8 MSPS scan speeds. The three channels can process multi-tap sensors, and the CDS stages ensure that sensor reset noise does not consume the bottom bits of the conversion range, directly improving image uniformity across the platen. The single +5V supply and 48-pin LQFP (7x7 mm) footprint support compact, low-cost desktop hardware, while 0 C to +85 C operation accommodates kiosk and border-checkpoint environments. Dual output mode simplifies interfacing to the embedded processor running the biometric matching stack.

主要差異化特點
- 16-bit resolution at 8 MSPS (對比VSP3100Y/2K)
- Dual output mode flexibility (對比VSP3210)
- Identical die availability in green packaging (對比VSP3200Y/2KG4)
設計說明
Route the CCD/CIS output-to-CDS input traces as short, shielded analog runs on a local analog ground island, and keep the VSP3200Y-2K digital output bus and its return currents on the opposite side of the board or separated by a ground guard. The 16-bit dynamic range means only a few millivolts of coupled digital switching noise can consume the least significant bits. Provide 100 nF ceramic decoupling at every supply pin plus a 10 uF bulk capacitor, per the TI VSP3200/VSP3210 datasheet typical application layout.
The VSP3200Y operates from a single +5V supply, so regulator noise passes directly into the analog front end. Use a linear regulator or well-filtered rail for the AFE supply, and avoid sharing the +5V rail with LED array drivers or stepper motors in the scanner head. Estimated: a 10 mVrms supply ripple at 100 kHz with 60 dB supply rejection appears as roughly 10 uVrms at the input, which is material relative to a 16-bit LSB at 5V full scale (about 76 uV at the ADC reference scale). Verify the actual PSRR figure in the manufacturer datasheet.
Do not confuse VSP3200Y dual output mode with the VSP3210 one-chip configuration when planning a substitute swap: the VSP3210 is pin-to-pin compatible with the VSP3100 only when operating in demultiplexed output mode, per the TI datasheet. Also note that the 2K ordering suffix denotes packaging/quantity code, not a different die - VSP3200Y and VSP3200Y/2K are electrically identical. Confirm the output-mode pin strapping on your PCB before placing either alternative.
