基于TDA8783的CCD相机电路设计

Designed for CCD cameras based on TDA8783

TDA8783是一款专用于CCD相机的10位模数接口芯片,具有强大的功能可编程特性。本文在分析TDA8783工作原理的基础上,选用FPGA器件作为硬件设计载体,完成了CCD视频信号处理硬件电路及PCB板设计。使用VHDL语言对TDA8783的初始化设置和驱动时序发生器进行了硬件描述。并针对ALTERA公司的EP2S60F484C3E进行了RTL级仿真及配置。

The TDA8783 is a 10-bit analog-to-digital interface for CCD cameras. Working elements of TDA8783 video processing interface for CCD cameras have been examined in detail, video processing circuit and it＇s hardware have been designed for CCD cameras. Field Programmable Logic Array （FPGA） is chosen as hardware design platform; initializing setting and driving schedule gen- erator is described with VHDL. The RTL simulation is fulfilled and design is fitted into EP2S60F484C3E .
