Design and Implement of Timing Generator of Integral Time Adjustable CCD Camera
积分时间可调的CCD相机驱动时序设计与实现

Based on the analysis of the structure and the driving timing of frame transfer CCD,its timing relationship and integral time value were calculated.Circularly embedded timing scheme that integral time could adjust flexibly was introduced.Field programmable gate array device was chosen as the hardware design platform.The schedule was designed with hardware described language.Considering strict and complex phase requirement,phase locked loop was used for precise phase shifting.Through Embedded logic analyzer the timing was sampled and verified.The driving timing generator of CCD camera with adjustable integral time was implemented on the CCD circuit board.
