It includes a complete analog front end with A/D conversion, combined with a full-function programmable timing generator and 18-channel vertical driver (V-driver). The timing generator is capable of supporting up to 24 vertical clock signals to control advanced CCDs. The onchip V-driver supports up to 18 channels for use with 5-field CCDs. A Precision Timing core allows adjustment of high speed clocks with approximately 400 ps resolution at 40 MHz operation. The AD9927 also contains eight general-purpose outputs, which can be used for shutter and system f...
