The AD9991 is a highly integrated CCD signal processor for digital still camera and camcorder 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 supporting both 4- and 6-phase vertical clocking. A Precision Timing core allows adjustment of high speed clocks with 800 ps resolution at 27 MHz operation.
The AD9991 is specified at pixel rates of up to 27 MHz. The analog front end includes black level clamping, CDS, VGA, and a 10-bit A/D converter. The timing generator provides all the necessary CCD clocks: RG, H-clocks, V-clocks, sensor gate pulses, substrate clock, and substrate bias control. Operation is programmed using a 3-wire serial interface.
Packaged in a space-saving 56-lead LFCSP, the AD9991 is specified over an operating temperature range of –20°C to +85°C.
