0 March 2000
DESCRIPTION
The WM8170 is a 10-bit analogue front end/digitiser IC, which processes and digitises the analogue output signals from area array CCD sensors at pixel sample rates of up to 21MSPS.
The device contains input blanking, correlated double sampling (CDS), programmable gain amplifier, black level clamp, on-board
voltage reference and a 10-bit, 21MSPS ADC.
Two auxiliary 8 bit DACs are provided which may be used for bias
voltage control or camera functions such as auto-focus.
Fine black level adjustment is performed digitally after the ADC.
This digital adjustment will follow DC shifts in the ...
