ADV7612 Power Supplies Filtering

I am designing with the ADV7612. The power supply recommendations,, calls an LC filter device NFE61PT472C1H9L to be used. This is a very large device with a current rating of 2A and capacitance rating of 4700pF, the largest in that family.


I would like to choose a smaller device for our very small board and found another Murata family, the NFE31P series. There I found the part NFE31PT222Z1E9L which has 2200pF rating but in a much smaller package.


Can anyone tell me if this is good enough? We don't have the time to do a rigorous power/noise analysis and are depending on the EVM design. But this point is problematic because of our limited board size.
