WM8235GEFL/V

Overview

The WM8235GEFL/V is a 16-bit analogue front-end and digitiser IC designed for processing CCD or CIS sensor signals. It features nine signal processing channels with Reset Level Clamping, Correlated Double Sampling, Programmable Gain, and Automatic Gain Control. Data is time-multiplexed into three high-speed 16-bit ADCs operating at up to 70 MSPS per channel, supporting an overall conversion rate of 210 MSPS. The device accepts a single 3.3V supply, consumes 390mA in active mode, and provides LVDS or CMOS output options via a flexible data port.

Feature Summary

• Nine-channel AFE with RLC, CDS, PGA, and AGC functions
• Three 16-bit ADCs providing 210 MSPS total throughput
• Integrated programmable sensor timing generator (CCD/CIS)
• Selectable LVDS (up to 490MHz) or CMOS (90MHz max) outputs
• Automatic Black-Level Calibration and internal voltage references

Applications

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

Procurement Notes

Verify the specific suffix 'V' indicates the tray-packaged version, distinct from the '/RV' tape-and-reel variant. Confirm lead-free status and MSL3 moisture sensitivity level requirements prior to assembly. Check current availability as distribution status may vary.

Selection Notes

Select this component for applications requiring multi-channel image sensor interfacing with integrated signal conditioning. Ensure the host system supports the required serial control interface and can handle the specified 390mA active current draw. Verify compatibility between the chosen output format (LVDS vs CMOS) and the downstream receiver logic speeds.

Part Context

This part belongs to the WM8235 family of high-performance analogue front-ends. The GEFL/V designation specifies the 56-lead QFN package (7mm x 7mm) with an industrial temperature range (-40°C to +85°C). It serves as a bridge between optical sensors and digital processing units in imaging systems.

Replacement Considerations

The WM8235GEFL/RV is the identical functional alternative packaged in tape and reel rather than trays. No other cross-model substitutes are documented in the provided source material.
