WM8232 - 70MSPS 3-Channel AFE

Description

The WM8232 is a 16-bit analogue front end/digitiser IC which processes and digitises the analogue output signals from CCD sensors or Contact Image Sensors (CIS) at pixel sample rates of up to 35MSPS.

Features

  • a sensor timing clock generator for both CCD and CIS sensors. The clock generator can accept a slow or fast reference clock input and also has a flexible timing adjustment function for output timing clocks to allow use of many different sensors.

w WM8232 70MSPS 3-Channel AFE with Sensor Timing Generation and LVDS/CMOS Data Output DESCRIPTION The WM8232 is a 16-bit analogue front end/digitiser IC which processes and digitises the analogue output signals from CCD sensors or Contact Image Sensors (CIS) at pixel sample rates of up to 35MSPS. The device has three analogue signal processing channels each of which contains Reset Level Clamping, Correlated Double Sampling (also Sample and Hold), Programmable Gain, Automatic Gain Control (AGC) and Offset adjust functions. The output from each of these channels is time multiplexed, in pairs, into three high-speed 16-bit Analogue to Digital Converters. The digital data is available in a variety of output formats via the flexible data port.
