Ethernet: Three-Speed Ethernet, MII Management
8.3
The electrical characteristics specified here apply to MII management interface signals MDIO
(management data input/output) and MDC (management data clock). The electrical characteristics for
MII, RMII, RGMII, SGMII, and RTBI are specified in
Controller (eTSEC) (10/100/1000 Mbps)—MII/RMII/RGMII/SGMII/RTBI Electrical
8.3.1
The MDC and MDIO are defined to operate at a supply voltage of 2.5V or 3.3 V. The DC electrical
characteristics for MDIO and MDC are provided in
