Enhanced Three-Speed Ethernet (eTSEC), MII Management
characteristics for MDIO and MDC are specified in
Characteristics.”
8.2
All GMII, MII, TBI, RGMII, RTBI, RMII, and FIFO drivers and receivers comply with the DC parametric
attributes specified in
RMII, and FIFO receiver may exceed the potential of the receiver’s power supply (that is, a GMII driver
powered from a 3.6-V supply driving V
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.
