Hi Vignesh,

Did you mean to ask what supply to use on the PHY? You can use DC supply for powering the PHY.

Hi Aniruddha

Thanks For Reply

But they Have given VDDA1P8 as 1.8V analog Supply and VDDA2PA as 2.5V analog supply VDD1P1 as 1.1V analog Supply VDD1P0 1V analog Supply

Analog Supply is nothing but one which varies with time interval ... Then how it will be a DC Supply

Hi Vighnesh,

All that the pin description is saying is that the rails is supplying a core rail rather than a digital domain.
'Analog supply' means nothing more than that.
The PHY requires DC supplies to be connected to our supply pins as defined in the datasheet.
