THS8200 VGA output Red as Orange

Other Parts Discussed in Thread: THS8200, TVP7002

Hi ,

One of my ctm use YUV422 ES to VGA.

The red color is not correct, it is looks like orange rather than red. While other colors looks good.

I have tried CSM registers, and adjust the resister value on FSADJx pins,there is no change.

Now I doubt the data inputs might have issues but it will take time to verify that(from Hisi mainchip which doesnt have colorbar built in), in the meanwhile I need to prove it by myself to persuade ctm to isolate the issue.

Could you give advice if any register can help improve that, or any suggestion that can help isolate the issue?

BR,

Eason

    Eason,

    There are really only 2 places that can be wrong.

    1) Digital inputs

    2) Color space converter

    Check the THS8200 configuration by using the example configuration files available on the TVP7002/THS8200 EVM page here...
