TVP7002采集五线制视频的连接方式

Other Parts Discussed in Thread: TVP7002, LMH1980

我们目前在利用TVP7002和DM368做视频采集,有几个问题想请教:

1、TVP7002如果采集1080p的视频是否需要外接场同步?

2、如果是一路五线制的视频信号采集,那么外部输入的行场同步如何接到TVP7002?7002提供了两组行场同步输入,应该如何接行场同步信号输入?

麻烦您在百忙之中帮我们看看这几个问题,不甚感激。

祝好!

  • 1.If the resolution is 1080p,the sync should be on Y channel.

    2.If the sesolution is 1080p25 or 1080p30,external circuit is required.Please following the reference schematic.

     

    3.It is better to use LMH1980 to replace the RC filter circuit.

    So,you should tell me what's your frame rate at first.
