Product details
Overview
VSP3100Y from Texas Instruments is a 14-bit, 10 MSPS CCD/CIS signal processor operating from a single +5V supply. It integrates three correlated double samplers (CDS), programmable gain amplifiers (PGA), and a 14-bit ADC for high-fidelity analog front-end processing in image capture systems. Designed for contact image sensors and interline-transfer CCDs, it supports 1- or 3-channel operation across 0°C to +85°C.
For engineers reviewing the VSP3100Y datasheet, VSP3100Y pinout, VSP3100Y application, or VSP3100Y equivalent, key selection criteria include its triple-CDS architecture, ±400 mV offset control range, selectable normal/demultiplexed digital output modes, +3V/+5V digital I/O compatibility, and LQFP-48 package with Level-1 moisture sensitivity rating.
Technical Context
The VSP3100Y implements a fully integrated analog signal chain optimized for optical sensor interfaces: each of its three input channels contains a dedicated CDS stage followed by a PGA with 0 dB to +13 dB gain control, enabling precise noise suppression and dynamic range adaptation for varying light conditions.
Its timing generator synchronizes sampling, clamping, and ADC conversion with external clocks (CK1, CK2, ADCCK), while internal 10-bit DACs provide programmable reference and offset control. The 14-bit parallel digital output (B0–B13) supports both normal and demultiplexed formats, and register configuration is handled via a 3-wire serial port (SCLK/SD/CM).
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar CCD/CIS signal processing applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9845B | 12-bit, 20 MSPS, dual-channel only; requires external reference and separate clock generator | Limited to 2-channel systems; lacks integrated clamp and CDS - needs external analog front-end components | Choose when higher speed (20 MSPS) is critical and system already includes precision clock synthesis and reference circuitry |
| VSP2200Y | 12-bit, 5 MSPS, single-channel; no demux output mode; smaller LQFP-32 package | Targeted at low-cost monochrome scanners; lacks RGB support and programmable offset range beyond ±200 mV | Choose for cost-sensitive, space-constrained 1-channel applications where 14-bit resolution and ±400 mV offset are not required |
Compared with AD9845B and VSP2200Y, the VSP3100Y uniquely combines 14-bit resolution, triple-channel CDS, ±400 mV offset control, and demultiplexed output in a single LQFP-48 package - making it the only option supporting full-color, high-dynamic-range scanner designs without external analog signal conditioning.

FAQ
What is the operating temperature range for the VSP3100Y?
The VSP3100Y is rated for operation from 0°C to +85°C ambient temperature. This range supports commercial and industrial imaging applications including document scanners and flatbed systems deployed in office and factory environments. Thermal performance remains stable across this range due to internal compensation circuits, and the device maintains full 14-bit linearity and ±400 mV offset control capability throughout. The VSP3100Y datasheet specifies no derating required within this interval.
Does the VSP3100Y support both CCD and CIS sensors?
Yes, the VSP3100Y explicitly supports both CCD and Contact Image Sensor (CIS) inputs. Its three-channel architecture accepts differential analog signals from tri-linear CIS arrays or interline-transfer CCDs, and its timing generator accommodates both CCD reset/integration sequences and CIS line-scan synchronization. The VSP3100Y datasheet confirms CIS compatibility through dedicated clamp and sampling timing controls, and references CIS-specific application notes in PDS-1583A.
What digital output formats does the VSP3100Y provide?
The VSP3100Y offers two selectable digital output modes: Normal (14-bit parallel on B0–B13) and Demultiplexed (7-bit dual-edge output reducing pin count by half). Mode selection is controlled via configuration register bits, and both formats operate at the same 10 MSPS sampling rate. The demultiplexed mode is particularly useful for FPGA-constrained designs where I/O resources are limited, and the VSP3100Y maintains full 14-bit accuracy in either mode.
Is the VSP3100Y pin-compatible with the VSP3000 series?
No, the VSP3100Y is not pin-compatible with the VSP3000 series. While the VSP3100Y is described as "interface compatible" with the VSP3000 - meaning register mapping, timing protocol, and functional behavior align - the physical pinout differs due to expanded functionality (e.g., additional analog inputs, extended digital bus). The VSP3100Y uses LQFP-48, whereas VSP3000 variants use smaller packages; direct PCB replacement is not supported without layout revision.
What power supply requirements does the VSP3100Y have?
The VSP3100Y operates from a single +5V analog supply (AVDD) and supports either +3V or +5V digital I/O (DVDD). It does not require separate analog/digital ground planes but recommends split grounding with single-point connection for optimal noise immunity. Total typical power dissipation is 450 mW at 10 MSPS, and the VSP3100Y includes internal voltage regulation for internal analog blocks - simplifying external power design compared to multi-rail alternatives.
