The AD9848 is highly integrated CCD signal processors for digital still camera applications. This 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 20 MHz. The analog front end includes black level clamping, CDS,PxGA, VGA, and a 10-bit A/Dconverter. The timing driver provides the high speed CCD clock drivers for RG and H1–H4. Operation is programmed using a 3-wire serial interface.
