The AD9920ABBCZ is a highly integrated Charge-Coupled Device (CCD) Signal Processor. It includes a complete analog front end (AFE) with analog-to-digital conversion, combined with a full-function programmable timing generator and 19-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 19 channels for use with six-field CCDs. A Precision Timing® core allows adjustment of high speed clocks with approximately 400 s resolution at 40.5MHz operation. The AD9920A also contains six 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.
