Four-channel Linear Array CCD-IT-P1 Driven by CPLD

CCD-IT-P1 produced by Dalsa Corporation is a linear scanning CCD which has 1024 pixels, and it outputs the image signals by four channels. Many problems existing in the drive aspect are analyzed in this paper. Aiming at the technology of four channels, the high requirement of driving frequency and the complex sequence etc.,we put forward a method in which the complex programmable logic device(CPLD) and very-high-speed integrated circuit hardware description language (VHDL) is used. This method of using complex VHDL achieves the function gotten by many gate-circuits, solves the jamming of the gate-circuits, and raises the degree of integraliztion,the performance of anti-jamming and the transplant. The experiment shows that to use CPLD for driving this CCD can achieve the favorable performance.
