Hello team,
I am confused because this device has 3 VDDIO options of 3.3V, 2.5V and 1.8V.
Is there any functional difference between them? How should I choose which voltage level to use for VDDIO?
Best Regards,
Kei Kuwahara

Hello Kei,
The VDDIO selection would depend on your system. Please note that this voltage would be the domain that all of the digital signals coming into and going out of the PHY use; MAC interface, LEDs, GPIOs, SMI.
