摘　　要：针对彩色扫描场合使用的线阵CCD芯片TCD2703D,提出了一种基于CPLD的线阵CCD驱动方案,结合了原理图和VHDL语言两种方式设计了驱动程序;采用74AHC04为驱动增强芯片,提高了电流驱动力。使用可编程逻辑器件EPM7064STC-10为核心器件,设计了硬件驱动器予以验证。实验结果表明,该设计方案有效地完成了对TCD2703D的驱动,并且具有高效开发、可重复编程,可修改的优势。In order to meet the needs of color scanning linear array CCD chip TCD2703D,this paper presents a driving plan for linear CCD based on CPLD,combines schematic and VHDL design language to design the driver,uses 74AHC04 device chip-driven enhancements to improve the current driving force.The is hardware designed to verify the drive.Experimental results show that the design effectively completed TCD2703D drive,and has the advantages of efficient development, being reprogrammable and modified.
