GENERAL DESCRIPTION

The AD9994 is a highly integrated CCD signal processor for digital still camera applications. It includes a complete analog front end with A/D conversion, combined with a full-function programmable timing generator. The timing generator is capable of up to 12-phase vertical clocking to support advanced CCDs with 4-field and 5-field readout. A Precision Timing core allows adjustment of high speed clocks with approximately 600 ps resolution at 36 MHz operation.
