Cirrus Logic, Inc. Analog Front End (AFE) WM8233GEFL/RV

The WM8233GEFL/RV is a 16-bit analog front end (AFE) and digitiser IC designed for processing and digitising signals from CCD and Contact Image Sensors (CIS) at pixel sample rates of up to 35MSPS per channel. It features six analog signal processing channels, each equipped with functions such as Reset Level Clamping, Correlated Double Sampling, Programmable Gain, Automatic Gain Control, and Offset adjustment. This device supports a maximum conversion rate of 210MSPS and operates on a single 3.3V supply with a current consumption of 350mA. The output data can be configured in either LVDS or CMOS formats, providing flexibility for various applications. The WM8233 includes an internal 5-bit DAC for reference level generation and offers programmable automatic Black-Level Calibration to adjust the DC offset of the output data. Additionally, the WM8233 incorporates a sensor timing clock generator compatible with both CCD and CIS sensors, allowing for precise timing adjustments. It is packaged in a 56-lead QFN format (8mm x 8mm) and is suitable for applications such as digital copiers, USB2.0 compatible scanners, and multi-function peripherals.
