Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

The AD9948 is a highly integrated CCD signal processor for digital still camera applications. Specified at pixel rates of up to 25 MHz, the AD9948 consists of 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 800 ps resolution. The analog front end includes black level clamping, CDS, PxGA, VGA, and a 25 MHz 10-bit A/D converter.

The timing driver provides the high speed CCD clock drivers for RG and H1H4. Operation is programmed using a 3-wire serial interface. Packaged in a space-saving 40-lead LFCSP package, the AD9948 is specified over an operating temperature range of 20°C to +85°C.
