Abstract

Briefly presented the Timing Generator's functions:it generates various kinds of impulse sequence for the focal plane unit and vision processor and acts as the synchronous coordinator for time in the CCD imaging unit. The CCD Timing Generator's architecture and its working process were analyzed. The interface relation between the CCD Timing Generator and CCD controller was also discussed.Based on the ISP technology and by utilizing the Expert soft system

the design process of the Timing Generator and the function simulation were presented. By using the ispLSI devices

the scheme was implemented in the end. The experiments indicate that the new method improved the integrated level of the system. The CCD camera system's high reliability

stability and low power supply are achieved. At the meantime

the period of design and experiment is sharply shorted.
