WM8231GEFL/RV

Overview

The WM8231GEFL/RV is a 16-bit analogue front-end and digitiser IC designed for CCD and CIS sensors. It features three signal processing channels with Reset Level Clamping, Correlated Double Sampling, Programmable Gain, Automatic Gain Control, and Offset Adjust. Each channel feeds into high-speed 16-bit ADCs, achieving up to 105 MSPS conversion rate. The device supports LVDS or CMOS output formats and includes an internal sensor timing clock generator. Operating on a single 3.3V supply, it consumes approximately 230mA in active mode.

Feature Summary

• Three-channel AFE with 16-bit resolution and 105 MSPS conversion rate
• Integrated Reset Level Clamping (RLC) and Correlated Double Sampling (CDS)
• Programmable Gain Amplifier (PGA) with Automatic Gain Control (AGC)
• Internal sensor timing generator supporting MCLK 5–35 MHz
• Selectable LVDS (up to 315 MHz) or CMOS (90 MHz max) data output

Applications

• Digital copiers
• USB 2.0 compatible scanners
• Multi-function peripherals
• High-speed CCD/CIS sensor interface

Procurement Notes

Verify the 'RV' suffix indicates tape and reel packaging with a quantity of 2,200 units. Confirm Moisture Sensitivity Level (MSL3) and peak soldering temperature (260°C) requirements during storage and assembly. Ensure the operating temperature range (-40°C to +85°C) matches the application environment.

Selection Notes

Select this component for applications requiring multi-channel sensor signal conditioning with integrated digitization. Ensure the host system supports the required serial control interface timing. Verify that the available power supply can deliver the typical 230mA current consumption at 3.3V. Check if LVDS or CMOS output compatibility aligns with the downstream digital processor.

Part Context

The WM8231GEFL/RV is the reel-packaged variant of the WM8231GEFL/V. Both share identical electrical specifications and functionality. The primary distinction lies in the shipping format; the RV suffix denotes tape and reel packaging suitable for automated surface mount assembly, whereas the V suffix typically indicates tube packaging.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Direct replacement requires matching the 56-lead QFN package dimensions and verifying pin-to-pin compatibility for all analogue inputs, digital outputs, and power pins.
