Abstract:

This paper discusses the current status of the linear CCD driving circuit and its working principle.The driving circuit based on CPLD has been selected as driving working program.EPM240T100C5N of MAXⅡdevices is used as the control center.Take TCD1500C for example,linear CCD driving circuit based on CPLD is designed,and the diagram of hardware design completed.Besides,the software debugging is implemented.By QUARTUSⅡsoftware platform,the simulation of this program shows that the linear CCD driving circuit based on CPLD can meet the driving pulse of CCD required.

Key words: linear CCD;CPLD;driving time;hardware description language
