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.”
