The Design of a High Accuracy Linear Array CCD Driving Circuit Based on CPLD and Verilog

A CPLD-based on design of high accuracy linear array CCD device's driving circuit using Toshiba Corporation's TCD1711DG is proposed.Firstly,the principle and timing of the TCD1711DG are analyzed.Then the driving circuit based on Altera Corporation's MAX7000S series EPM7032STC44 is designed with finite state machine in Verilog HDL by adopting developing system QuartusⅡ.Finally,the driver circuit's simulation is completed in ModelSim SE,and the output timing pulse of CPLD is tested with oscilloscope.The results obtained from simulation and test demonstrate that the design meets the timing requirements of the TCD1711DG.
