视频同步分离芯片LM1881及其应用

Video sync separator LM1881 and its application

LM1881是针对电视信号的视频同步分离芯片,它可以直接对电视信号进行同步分离,准确地获得所需的视频图像信号,使用者可根据需要对该同步信号进行时序逻辑控制.LM1881广泛用于对视频信号的同步分离中,比如便携式图像采集卡、视频监控录像控制仪、基于成像系统的视频图像采集等.介绍了LM1881的主要特性,基本原理和引脚功能,给出了它的几种应用.

LM1881 is a video sync separator which processes video signals,and it can separate sync signal directly.Users can carry out time sequence logical control with the sync signals by request.LM1881 is used in the synchronous separation of signals,for example,portable picture gathering cards video controllers,video picture gathering, etc. The main characters,basic principles,pin functions of LM1881 and its application are introduced.
