GENERAL DESCRIPTION
The AD9845B is an improved version of the AD9845A CCD
signal processor. It features a 30 MHz single-channel architec-
ture designed to sample and condition the outputs of interlaced
and progressive scan area CCD arrays. The AD9845B’s signal
chain consists of an input clamp, a correlated double sampler
(CDS),
PxGA
, a digitally controlled VGA, a black level clamp,
and a 12-bit A/D converter. Additional input modes are also
provided for processing analog video signals.
The internal registers are programmed through a 3-wire
serial digital interface. Programmable features include gain
adjustment, black level adjustment, input configuration, and
power-down modes.
The AD9845B operates from a single 3 V power supply, typi-
cally dissipates 153 mW, and is packaged in a 48-lead LQFP.
