8 Ethernet and MII Management
This section provides the AC and DC electrical characteristics for Ethernet interfaces.
8.1 Ethernet Controller (10/100 Mbps)—MII/RMII Electrical
Characteristics
The electrical characteristics specified here apply to all MII (media independent interface) and RMII
(reduced media independent interface), except MDIO (management data input/output) and MDC
(management data clock). The MII and RMII are defined for 3.3 V. The electrical characteristics for MDIO
and MDC are specified in Section 8.3, “Ethernet Management Interface Electrical Characteristics.”
8.1.1 DC Electrical Characteristics
All MII and RMII drivers and receivers comply with the DC parametric attributes specified in The
following table.
