Design of the time sequence driving circuit for a king of long linear CCD based on FPGA

Design of time sequence driving circuit is the key technology for applications of CCD.Driving schedules of TH7834C(one kind of long linear CCD produced by ATMEL Co Ltd)are examined.The time sequence driving circuit is designed for TH7834C.Field Programmable Gate Array(FPGA)is chosen as the hardware design platform,the time sequence driving circuit is described with VHDL.The design is successfully fulfills function simulation with EDA software and fits into EPF10K30RC240-3(a kind of FPGA products made by Altera Corporation).The result of the project realization indicates that the time sequence driving circuit is suitable for the driving of TH7834C,and the design is characterized by simple framework,low power consumption,strong anti-jamming ability,higher of practical value.The result can be proposed as a skill applied to CCD components of various models as well.
