Abstract
The Application-Specific Integrated Circuit (ASIC) development plan of the astronomical CCD control system is a special chip development project launched officially by the National Astronomical Observatory of the Chinese Academy of sciences. One of the scientific objectives: Bias and Clock Driver ASIC (CDA), has been designed and manufactured twice. The test shows the performance of CDA completely reach the design requirement. Now this chip can be mass produced at low cost. We claim the CDA is successfully developed in our laboratory. CDA provides bias voltage and clock drives for CCD working. 48 DACs which produce pulse at any amplitude can be used for most CCD controller. The combination of CDA and ASIC lead to integrated multi-CCD system or sub-mini single CCD controller. This high integrated chip make the CCD controller smaller, lower power consumption, more stable and easier to be developed.
