I'm learning about the RGMII interface of ethernet. Can anybody please tell me What IO standard does the TX and RX line of RGMII interface support? Please help. I'm just a beginner

The two RGMII reference designs I have are both 2.5V LVCMOS. You should check the datasheet of the PHY chip you're using to confirm.

Depends on RGMII version, but either 2.5V CMOS or 1.5V HSTL
