GENERAL DESCRIPTION

The AD9942 is a highly integrated dual-channel CCD signal processor for digital still camera applications. Each channel is specified at pixel rates of up to 40 MHz. The AD9942 consists of a complete analog front end with analog-to-digital conversion, combined with a programmable timing driver. The Precision Timing core allows high speed clocks to be adjusted with 550 ps resolution.
