12-Bit CCD Signal Processor with Precision TimingTM Generator
The AD9994 is a highly integrated CCD signal processor designed specifically for digital still camera applications. It combines an analog front end with analog-to-digital conversion and a fully programmable timing generator to support advanced CCD readouts.
Key features include support for 10-phase or 12-phase vertical transfer clocking, a correlated double sampler (CDS), a variable gain amplifier (VGA) ranging from 6 dB to 42 dB, and a 12-bit analog-to-digital converter operating up to 36 MHz. The device also features on-chip timing generation with approximately 600 ps resolution.
