Hi Team,

When AVDD and VDDIO are powered by 1.8V.

Do the power supply between RD- and RD+ need also change to 1.8V?

Thank you,

The termination voltage needs to follow the AVD. So if the AVD is 1.8V, then this needs to be 1.8V as well.

The block diagram is not correct and we are working to fix it to show the termination voltage needs to be changed to AVD.

Thanks

David
