Ethernet Interface and MII Management
Specification Version 1.2 (3/20/1998). The electrical characteristics for MDIO and MDC are specified in
8.1.1
Ethernet Interface DC Electrical Characteristics
All GMII, MII, TBI, RGMII, RMII and RTBI drivers and receivers comply with the DC parametric
attributes specified in Table 23 and Table 24. The potential applied to the input of a GMII, MII, TBI,
RGMII, RMII or RTBI receiver may exceed the potential of the receiver’s power supply (that is, a GMII
driver powered from a 3.6-V supply driving VOH into a GMII receiver powered from a 2.5-V supply).
Tolerance for dissimilar GMII driver and receiver supply potentials is implicit in these specifications. The
RGMII and RTBI signals are based on a 2.5-V CMOS interface voltage as defined by JEDEC
EIA/JESD8-5.
