ADV7181C Set up

We are using the ADV7181C video decoder in a design to decode SVGA (800x600@60Hz) input signal. I believe that I have set most of the parameters in the device correctly, i.e. I am seeing the right pixel clock frequency and the timings of HS and VS look OK. We want to pass the RGB components through to the output without any CSC – the CSC block is placed right in front of the CP within the device. It is not clear how this CSC should be used so that no colour space conversion takes place. I am assuming that I have to program the coefficients but there does not seem to be any guidelines on how to select the coefficients.

 

I have an XML spreadsheet which is used to set up the devices on the board at power up. Would it be possible for AD to check the settings I am using?
