It includes a complete analog front end with analog to digital conversion combined with a full-function programmable timing generator. The timing generator is capable of supporting up to 24 vertical clock signals to control advanced CCDs. A Precision Timing™ core allows adjustment of high speed clocks with approximately 400 ps resolution at 40 MHz operation. The AD9992 also contains eight general-purpose inputs/outputs that can be used for shutter and system functions. The AD9992 is specified at pixel rates of up to 40 MHz. The analog front end includes black level clamping, CDS, VGA, and a 12-bit analog-to-digital ...
