Features and Benefits
Product DetailsThe AD9920 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 18-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 18 channels for use with 5-field CCDs. A Precision Timing core allows adjustment of high speed clocks with approximately 400 ps resolution at 40.5 MHz operation. The AD9920 also contains eight GPOs that can be used for shutter and system functions.
The analog front end includes black level clamping, variable gain CDS, and a 12-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 AD9920 is specified over an operating temperature range of −25°C to +85°C.
