WM8233GEFL/V

Overview

The WM8233GEFL/V is a 16-bit analogue front end and digitiser IC designed for processing CCD or CIS sensor signals. It features six signal processing channels with Reset Level Clamping, Correlated Double Sampling, Programmable Gain, Automatic Gain Control, and Offset Adjust. The device multiplexes channel outputs into three high-speed 16-bit ADCs operating at up to 70 MSPS. It supports user-selectable LVDS or CMOS data output architectures and includes an internal sensor timing clock generator. The component operates on a single 3.3V supply and consumes approximately 350mA.

Feature Summary

• Six-channel AFE with RLC, CDS/S&H, PGA, AGC, and offset adjust
• Three 16-bit ADCs providing 70 MSPS conversion rate
• Configurable LVDS (up to 490MHz) or CMOS (90MHz max) output
• Integrated programmable sensor timing generator for CCD/CIS

Applications

• Digital copiers
• USB2.0 compatible scanners
• Multi-function peripherals
• High-speed CCD/CIS sensor interface

Procurement Notes

Verify the specific suffix 'V' indicates tray packaging when sourcing. Confirm moisture sensitivity level MSL3 compliance and peak soldering temperature limits of 260°C during assembly. Ensure serial interface pins are correctly addressed using DSLCT1 and DSLCT2 for multi-device systems.

Selection Notes

Select this model for applications requiring six independent analog channels with integrated signal conditioning. Verify that the required pixel sample rate per channel does not exceed 35 MSPS. Choose between LVDS and CMOS outputs based on board trace length and noise immunity requirements.

Part Context

This component belongs to the Cirrus Logic WM8233 series of sensor AFEs. It is functionally similar to the WM8234 but offers different channel counts or speeds. The GEFL/V suffix denotes the 56-lead QFN package variant supplied in trays, distinct from the RV reel version.

Replacement Considerations

Public confirmed substitute part numbers: None.
