Keywords:analog switches? video signal? switching?

As PC games, video editing, streaming movies on TV and DVD playback are becoming more common, there is an increasing demand to display such video graphics on larger display screens like those of TV rather than the PC monitors.

Analog switches are often used to route RGB data or component or composite video data from different video sources, or to feed encoders with the video data to different displays. The former is a multiplexing function while the latter is a demultiplexing function.

Interest in using analog switches in video signal routing applications is growing due the rising trend of using lower pin count and the possibility of achieving cost reduction by sharing the same video encoder/decoder or RAMDAC. This application note describes the video signal standards and explains the various important parameters, which are necessary to consider, in video signal switching.
