WM8233GEFL/RV

Overview

The WM8233GEFL/RV 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. Each channel feeds into one of three high-speed 16-bit ADCs via time multiplexing. The device supports pixel sample rates up to 35MSPS per channel with an overall conversion rate of 210MSPS. It operates on a single 3.3V supply and includes an internal sensor timing clock generator.

Feature Summary

• Six-channel AFE with RLC, CDS/Sample-and-Hold, PGA, AGC, and offset adjust
• Three 16-bit ADCs supporting 210MSPS total conversion rate (35MSPS per channel)
• User-selectable LVDS (up to 490MHz) or CMOS (90MHz max) data output
• Integrated programmable sensor timing generator for CCD and CIS sensors

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 standard quantity of 2,200 units. Confirm the package type is the 56-lead QFN (8 x 8 x 0.85 mm). Ensure compatibility with the -40°C to +85°C operating temperature range and MSL3 moisture sensitivity level before procurement.

Selection Notes

Select this component when interfacing with multi-channel CCD or CIS sensors requiring integrated signal conditioning. The WM8233 eliminates external analog components by providing RLC, CDS, and PGA functions. Choose between LVDS or CMOS outputs based on downstream digital logic requirements and trace length constraints.

Part Context

This part belongs to the Cirrus Logic WM8233 family of sensor AFEs. It is functionally similar to the WM8234 but offers specific timing and output configurations. The GEFL/RV designation specifies the lead-free, tape and reel variant of the 56-lead QFN package.
