The AD9849 are highly integrated CCD signal processors for digital still camera applications. Both include a complete analog front end with A/D conversion, combined with a programmable timing driver. The Precision Timing core allows adjustment of high speed clocks with approximately 1 ns resolution.

The AD9849 is specified at 30 MHz. The analog front end includes black level clamping, CDS, PxGA, VGA, and a 10-bit or 12-bit A/D converter. The timing driver provides the high speed CCD clock drivers for RG and H1–H4. Operation is programmed using a 3-wire serial interface.

Packaged in a space saving 48-lead LQFP, the AD9849 are specified over an operating temperature range of –20°C to +85°C.
