Hi,
I have one doubt in am437x design that is in gigabit ethernet PHY chip design.
As per the datasheet of KSZ9031RNXCA (PHY chip) AVDDl, DVD-DL, and AVDDL_PLL maximum voltage are 1.8V.
But the design applied 3.3V through P channel Mosfet.
I know it is working fine in EVM.
Is there any reason to give 3.3V?
