ADV7513 Power Supply Filtering

Hi,

 

The Hardware User Guide of ADV7513 specifies to use an LC filter of 10µH inductor and 10µF capacitor for noise suppresion and also to separate the power domains.

In the ADV7511 EVM, we see that apart from the LC circuit, an additional EMC filter is also used. Can you please tell us the reason for it? Also, can you confirm if it is necessary to use the additional EMC filter, as space is also a concern in our board design?
