GENERAL DESCRIPTION

The AD9920A is a highly integrated charge-coupled device (CCD) signal processor for digital still camera applications. It includes a complete analog front end (AFE) with analog-to-digital conversion, combined with a full-function programmable timing generator and 19-channel vertical driver (V-driver). The timing generator is capable of supporting up to 24 vertical clock signals to control advanced CCDs. The on-chip V-driver supports up to 19 channels for use with six-field CCDs. A Precision Timing® core allows adjustment of high speed clocks with approximately 400 ps resolution at 40.5 MHz operation. The AD9920A also contains six GPOs that can be used for shutter and system functions.
