Overview
w WM8233 70MSPS 6-Channel AFE with Sensor Timing Generation and LVDS/CMOS Data Output DESCRIPTION The WM8233 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 six 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.
The WM8233 has a user selectable LVDS or CMOS output architecture.
An internal 8-bit DAC is supplied for internal reference level generation.
This may be used during CDS to reference CIS signals or during Clamping to clamp CCD signals.
