Overview
w 40MSPS 16-bit CCD Digitiser WM8214 DESCRIPTION The WM8214 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 40MSPS.
The device includes three analogue signal processing channels each of which contains Reset Level Clamping, Correlated Double Sampling and Programmable Gain and Offset adjust functions.
Three multiplexers allow single channel processing.
The output from each of these channels is time multiplexed into a single high-speed 16-bit Analogue to Digital Converter.
The digital output data is available in 8-bit wide multiplexed format and there is also an optional single byte output mode, or 4-bit multiplexed LEGACY mode.
An internal 4-bit DAC is supplied for internal reference level generation.
This may be used during CDS to reference CIS signals or during Reset Level Clamping to clamp CCD signals.
An external reference level may also be supplied.
