AM5728: Driving Ethernet PHY at 1.8V

Part Number: AM5728

Hello,

  we want to drive the ethernet PHYs with 1.8V instead of 3.3V like on the EVM. Am I right assuming that we only have to adjust the IO delays and feed the 1.8V to the RGMII Power Group pins? Or am I missing something?

Thanks in advance,
