GENERAL DESCRIPTION

The AD9845B is an improved version of the AD9845A CCD signal processor. It features a 30 MHz single-channel architecture 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.
