24MSPS 16-bit CCD Digitiser
WM8213
DESCRIPTION
The WM8213 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
www.DataSheet4U.scaommple rates of up to 24MSPS.
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.
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 WM8213 typically only
consumes 350mW.
