Hello,

I have an inquiry regarding the DP83822IR TPI Network Circuit and would appreciate your confirmation.

In the diagram below, it states "3.3V Supply." However, we are using 1.8V for AVD and VDDIO. Should we provide 1.8V instead of 3.3V in this case?

Thank you for your support.

Best regards.

Hi,

The PU termination voltage on MDI as well as the center tap voltage should be both AVD supply. In this case, since you are using 1.8V for AVD, then both the termination voltage and the center tap voltage will be 1.8V as well.

Thanks

David
