14-Bit, CCD Signal Processor with ™ Core

The AD9979 is a highly integrated CCD signal processor for high speed digital video camera applications. Specified at pixel rates of up to 65 MHz, the AD9979 consists of a complete analog front end with analog-to-digital conversion, combined with a programmable timing driver. The Precision Timing core allows adjustment of high speed clocks with approximately 240 ps resolution at 65 MHz operation.

The analog front end includes black-level clamping, CDS, VGA, and a 65 MSPS, 14-bit analog-to-digital converter (ADC). The timing driver provides the high speed CCD clock drivers for RG, HL, and H1 to H4. Operation is programmed using a 3-wire serial interface.

Available in a space-saving, 7 mm × 7 mm, 48-lead LFCSP, the AD9979 is specified over an operating temperature range of −25°C to +85°C.
