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.
