Product Details
●The AD9928 is a highly integrated CCD signal processor for digital still camera applications. It includes a dual analog front end with analog-to-digital conversion, combined with a full-function programmable timing generator and 18-channel vertical driver (V-driver) for a 2-channel output CCD. The timing generator is capable of supporting up to 24 vertical clock signals internally, and the on-chip V-driver supports up to 18 high voltage outputs. A _Precision Timing_™ core allows adjustment of high speed clocks with approximately 390 ps resolution at 40 MHz operation. The AD9928 also contains eight general-purpose outputs, which can be used for shutter and system functions.
●Each 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 AD9928 is specified over an operating temperature range of –25°C to +85°C.
