GENERAL DESCRIPTION
The AD9945 is a complete analog signal processor for CCD
applications. It features a 40 MHz single-channel architecture
designed to sample and condition the outputs of interlaced and
progressive scan area CCD arrays. The AD9945’s signal chain
consists of a correlated double sampler (CDS), a digitally con-
trolled variable gain amplifier (VGA), a black level clamp, and a
12-bit A/D converter.
The internal registers are programmed through a 3-wire serial digital
interface. Programmable features include gain adjustment, black
level adjustment, input clock polarity, and power-down modes.
The AD9945 operates from a single 3 V power supply, typi-
cally dissipates
mW, and is packaged in a space-saving
32-lead LFCSP.
