视频同步分离芯片的设计与仿真

Design and Simulation of Video Sync Separator Chip

本文设计了一款针对复合视频信号的视频同步分离芯片。它可以对NTSC、PAL、SECAM制式的视频信号进行同步分离,获得所需的同步信号,还能准确地输出复合同步、后沿输出、行同步、场同步和奇/偶场输出信号。

This paper introduces the design of a video sync separator chip for composite video signals processing. It can separate sync signals from NTSC, PAL and SECAM video signals, and produces composite sync output signal, back porch output signal, horizontal sync signal, vertical sync signal and odd/even field output signal.
