DESCRIPTION
The WM8215 is a 10-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 60MSPS.
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. The output from each of these
channels is time multiplexed into a single high-speed 10-bit
Analogue to Digital Converter. The digital output data is
available in 10-bit wide parallel format.
An internal 4-bit DAC is supplied for internal reference level
generation. This may be used to reference CIS signals, in
non-CDS mode or to clamp CCD signals during Reset Level
Clamping. An external reference level may also be supplied.
ADC references are generated internally, ensuring optimum
performance from the device.
Using an analogue supply voltage of 3.3V and a digital
interface supply of 3.3V, the WM8215 typically only
consumes 400mW.
