The AD9927 is a highly integrated CCD signal processor for digital still camera applications. 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 functions.
The analog front end includes black level clamping, CDS, VGA, and a 14-bit ADC. The timing generator provides all the necessary CCD clocks: RG, H-clocks, V-clocks, sensor gate pulses, substrate clock, and substrate bias control.
The AD9927 is specified over an operating temperature range of –25°C to +85°C.
