The AD9891 and AD9895 are highly integrated CCD signalprocessors for digital still camera applications. Both include acomplete analog front end with A/D conversion combined witha full-function programmable timing generator. A PrecisionTiming core allows adjustment of high speed clocks with 1 nsresolution at 20 MHz operation and 700 ps resolution at 30MHz operation.The AD9891 is specified at pixel rates of up to 20 MHz, andthe AD9895 is specified at 30 MHz. The analog front endincludes black level clamping, CDS, PxGA, VGA, and a 10-Bitor 12-Bit A/D converter. The timing generator provides all thenecessary CCD clocks: RG, H-clocks, V-clocks, sensor gatepulses, substrate clock, and substrate bias control. Operation isprogrammed using a 3-wire serial interface.Packaged in a space-saving 64-lead CSPBGA, the AD9891 andAD9895 are specified over an operating temperature range of–20°C to +85°C.
