Changing DAC/ADC clks for external clk input

I'm trying to make a change in the reference design provided by avnet, i'm using the logic for the ADC/DAC included in the reference but my clk is now coming from the FMC150.


I've managed to use the clock coming from the FMC150, but the configuration in the design for the ADC/DAC is using clks 491.52MHz/245.76MHz, my external input clks is 400MHz.

For the DAC config, I have to change the OSERDES2 for my clk and change the interpolation config in the DAC3283?
