3.3V Integrated Signal Processor for Area Array CCDs

WM8170
3.3V Integrated Signal Processor for Area Array CCDs
Product Preview Rev 1.0 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 video
input without introducing digital correction noise into the
image.
The WM8170 is designed to interface to a wide range of area
array CCDs and can operate at lower power for slower
sample rates by setting the reference bias current via an
external resistor connected to the ISET pin.
All signal timing within the device is derived from the CCD
clock signals. The WM8170 is controlled via a configurable
serial interface, which is compatible with all of Wolfson’
s
imaging devices.
The user is able to control the device functions and monitor
on-chip register settings via the easy-to-use digital
management interface.
