As per the OSM specification, some interfaces support multiple I/O voltage levels.
RGMII can operate at 1.8V, 2.5V, or 3.3V.
By default, G50M i.MX 93 Size-L and Size-S OSM supports RGMII at 1.8V.
A level translator (SN74AXC8T245PWR) can be used to interface with a 3.3V PHY. However, due to timing constraints, the achievable Ethernet speed may be limited to 10/100 Mbps.
Please find attached the TI application note on RGMII voltage translation.
Devices such as SN74AVC8T245PWR can be used for RGMII level translation from 1.8V to 3.3V, while SN74AXC8T245PWR can be used for translation from 2.5V to 3.3V.
