本文首先描述了CCD摄像机的背景和发展历程,之后又对HDTV的相关概念进行了简要的介绍。重点对本项目研制的高速CCD摄像机系统中的数字分量转模拟分量的电路以及相关程序进行了设计。由于要对1080P格式的数字分量进行转换,且每组数字信号要求最少8bit,因此采用TI公司的视频D/A转换芯片THS8200-EP,并使用Verilog HDL硬件编程语言对THS8200-EP中的寄存器进行配置。
本课题完成了数模转换电路的设计和THS8200-EP内寄存器读写程序的编写工作,仿真结果表明设计的程序满足读写时序。

Title Display Circuit and Program Design of Analog Color Component in 1080P Format
Abstract CCD camera has very extensive applications in the field of consumer, non-contact measurement and the image sensor , which also contributed to the development of related technologies field. The CCD device has wide spectral response, high sensitivity, special scanning, small distortion, anti-vibration, anti-glare, no blur and many other advantages.
The present paper describes the background and development of CCD cameras, then briefly introduces the concept of HDTV. In this thesis, a focused study for the circuit and program design of digital transfer analog components of the said project. Due to the conversion of the digital components in 1080p format, and digital signal required at least 8bit in each group, we choose the video D/A conversion chip THS8200-EP made by TI. And using Verilog HDL hardware programming language to configure registers in THS8200-EP.
This paper completes the design of D/A conversion circuit and the read and write procedures of registers in THS8200-EP, the simulation results show that the design of programs meet the read and write timing.
