Product details
Overview
VSP3100Y/2K from Texas Instruments (formerly Burr-Brown) is a 14-bit, 10 MSPS CCD/CIS signal processor with triple correlated double samplers (CDS), programmable gain amplifiers (PGA), and integrated 14-bit ADC. It operates from a single +5V supply, supports 0°C to +85°C industrial temperature range, and is packaged in LQFP-48. It processes analog outputs from linear CCD or contact image sensors in document scanners and industrial inspection systems.
For engineers reviewing the VSP3100Y/2K datasheet, VSP3100Y/2K pinout, VSP3100Y/2K application, or VSP3100Y/2K equivalent, key selection criteria include its 14-bit resolution, 10 MSPS sampling rate, ±400 mV offset control, selectable 1-/3-channel operation mode, and compatibility with legacy VSP3000-based designs.
Technical Context
The VSP3100Y/2K implements three independent CDS/PGA channels for simultaneous RGB or multi-tap CCD/CIS signal conditioning, each supporting 0 dB to +13 dB programmable gain and clamp-controlled DC offset adjustment. Its timing generator provides internal clocking for ADC conversion (ADCCK), sample/hold control (CK1, CK2), and clamping (CLP).
Digital output is configurable as normal or demultiplexed 14-bit parallel data (B0–B13), with +3V/+5V logic compatibility and register-controlled configuration via SPI-like interface (SCLK, SD, WRT, RD, OE). The device includes on-chip 10-bit DACs for reference voltage generation (REFP/REFN) and internal bias (VDRV).

Equivalent & Alternatives
The following parts are listed as comparable options for similar CCD/CIS signal processor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TDC1300EVM | 16-bit, 20 MSPS, but requires external CDS and separate PGA; no integrated VDRV or timing generator. | Targeted at high-speed scientific imaging, not cost-sensitive embedded scanners. | Choose only if higher resolution and speed outweigh added board area and design complexity. |
| AD9945ASTZ | 14-bit, 25 MSPS, dual-channel CDS/PGA; lacks third channel and integrated CIS driver (VDRV). | Optimized for interline-transfer CCDs in broadcast cameras-not suitable for tri-linear or CIS-based systems. | Select when using dual-output interline CCDs and external bias generation is acceptable. |
Compared with TDC1300EVM and AD9945ASTZ, the VSP3100Y/2K uniquely integrates triple CDS, 0–13 dB PGA, VDRV, and timing generator in LQFP-48-making it the only single-chip solution for compact, low-cost tri-linear CCD or CIS scanner engines requiring ≤10 MSPS throughput.

FAQ
What is the maximum sampling rate supported by the VSP3100Y/2K?
The VSP3100Y/2K supports a typical maximum sampling rate of 10 MSPS, as confirmed in the PDS-1583A datasheet. This rate applies under standard operating conditions (VDD = +5 V, TA = 25°C) and enables real-time digitization of high-speed line-scan sensors. The device maintains full 14-bit performance at this rate, with timing controlled internally by the integrated timing generator. VSP3100Y/2K does not support oversampling or decimation modes beyond this specification.
Does the VSP3100Y/2K support Contact Image Sensor (CIS) interfaces natively?
Yes, the VSP3100Y/2K natively supports CIS interfaces through its triple-channel analog input structure (RINP/RINN, GINP/GINN, BINP/BINN) and integrated VDRV output pin, which supplies regulated bias voltage directly to CIS sensor arrays. Its 1-/3-channel operation mode and clamp-controlled CDS architecture are explicitly designed for CIS signal conditioning, as stated in the product description and feature list. VSP3100Y/2K eliminates the need for external CIS driver ICs in compact module designs.
Is the VSP3100Y/2K pin-compatible with the VSP3000 series?
The VSP3100Y/2K is interface-compatible with the VSP3000, meaning register maps, control signaling (SCLK/SD/WRT/RD/OE), and functional pin roles align-but it is not pin-to-pin compatible due to differences in pin count (VSP3000 is 44-pin PQFP) and LQFP-48 package footprint. VSP3100Y/2K requires PCB layout revision for migration, though firmware and configuration logic can be reused. TI documentation confirms functional compatibility, not mechanical drop-in replacement.
What digital output voltage levels does the VSP3100Y/2K support?
The VSP3100Y/2K supports both +3 V and +5 V digital output logic levels, selectable via internal configuration registers. Its B0–B13 parallel bus and control pins (WRT, RD, OE) are designed to interface directly with either 3.3 V or 5 V FPGA, microcontroller, or ASIC I/O banks without level-shifting. This dual-voltage capability is documented in the "Features" section and verified in the electrical characteristics table of PDS-1583A. VSP3100Y/2K maintains full timing specifications across both voltage modes.
Why is the VSP3100Y/2K marked as NRND (Not Recommended for New Designs)?
The VSP3100Y/2K is designated NRND by Texas Instruments due to end-of-life planning for this legacy image processor, as reflected in the 2014 Package Option Addendum. While still in production for existing customers, TI recommends newer alternatives like the TDC1300 family for new designs. However, VSP3100Y/2K remains viable for legacy system refresh, repair, or applications where its specific integration (triple CDS + VDRV + timing generator) offers unmatched cost and space advantages. Aetrix Electronics provides continuity support for VSP3100Y/2K.
