WM8235GEFL/RV

Overview

The WM8235GEFL/RV is a 16-bit analogue front-end and digitiser IC designed for CCD and CIS sensors. It processes signals at up to 23MSPS per channel using nine signal processing channels featuring Reset Level Clamping, Correlated Double Sampling, Programmable Gain, Automatic Gain Control, and Offset adjust. Data is time-multiplexed into three high-speed 16-bit ADCs. The device operates on a single 3.3V supply with a total current consumption of 390mA. It offers flexible LVDS or CMOS output architectures and includes an internal sensor timing clock generator.

Feature Summary

• Nine analogue signal processing channels with Reset Level Clamping, CDS, PGA, AGC, and offset adjust
• Three high-speed 16-bit ADCs with a conversion rate of 210MSPS
• User-selectable LVDS (5-pair) or CMOS output architecture
• Internal programmable sensor timing clock generator for CCD/CIS compatibility

Applications

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

Procurement Notes

Verify the ordering suffix RV indicates tape and reel packaging with a reel quantity of 2,200 units. Confirm the temperature range is -40°C to +85°C and the package is a 56-lead QFN (7mm x 7mm). Ensure compliance with MSL3 moisture sensitivity level requirements during storage and handling.

Selection Notes

Select this component for applications requiring multi-channel signal conditioning from image sensors. The device supports pixel sample rates up to 23MSPS per channel. Consider the LVDS option for high-speed data transmission up to 490MHz or CMOS for lower frequency outputs up to 90MHz. Verify power supply constraints match the 3.3V single supply requirement.

Part Context

The WM8235GEFL/RV is the tape and reel variant of the Cirrus Logic WM8235. It shares identical electrical specifications with the tray-packaged WM8235GEFL/V. Both variants are manufactured in a 56-lead QFN package and operate within the same industrial temperature range of -40°C to +85°C.
