DRA821U: RMII Interface Application Example

Hi 

There's a question that customer wants to get feedback from TI.

Could you please provide us with reference circuit regarding RMII insterface? 

In my initial review, I found Figure 12-490 and Figure 12-491in TRM as below.

Regarding clock speed, It seems 50MHz is only applicable to RMII interface. 

Please give your opinions since customer could not fix RMII part for their schematic.  Especially more focusing on Clock supply from DRA821U ' internal and external connection point of view.

As an example, When I looked at the customer's diagram, 25MHz clock is connected to PHY unlike TRM.

Thanks.
