GENERAL DESCRIPTION

The AD9898 is a highly integrated CCD signal processor for

digital still camera and digital video camera applications. It

includes a complete analog front end with A/D conversion

combined with a full function programmable timing generator.

A Precision Timing core allows adjustment of high speed clocks

with 1 ns resolution at 20 MHz operation.

The AD9898 is specified at pixel rates as high as 20 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 pulse. Operation is

programmed using a 3-wire serial interface.

Packaged in a space saving 48-Lead LFCSP, the AD9898 is

specified over an operating temperature range of –20

°C to +85°C.
