GENERAL DESCRIPTION
The AD9974 is a highly integrated, dual-channel, chargecoupled device (CCD) signal processor for high speed digital video camera applications. Each channel is specified at pixel rates of up to 65 MHz. The AD9974 consists of a complete analog front end (AFE) 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.
