AB - The increased number of pixels in CCD sensors has meant a corresponding increase in the time required to read out the sensor with low noise. Therefore two to four readout circuits are now being included on a single CCD. The CCD image can be broken up into sections and moved separately to each readout amplifier, reducing the overall readout time. This creates the need for CCD camera controllers that can control more than one CCD readout at a time. The system architecture of such a controller is described. The two major boards - a digital timing board shared between all the readouts, and a mostly analog readout dedicated one per readout - are discussed in detail. The timing board contains a fast digital signal processor that contains the readout program and timing information in internal memory and updates the CCD clocks at a 10 MHz rate. The performance of the analog cicuitry and a sample readout program described.
