AD9925BBCZRL

GENERAL DESCRIPTION

The AD9925 is a complete 36 MHz front end solution for digital still camera and other CCD imaging applications. Based on the AD9995 product, the AD9925 includes the analog front end and a fully programmable timing generator (AFETG), combined with a 10-channel vertical driver (V-driver). A Precision Timing core allows adjustment of high speed clocks with approximately 600 ps resolution at 36 MHz operation.
