7.3 Ethernet Management Interface Electrical Characteristics

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

GMII, RGMII, TBI and RTBI are specified in Section 7.1, “Three-Speed Ethernet Controller (TSEC)

(10/100/1Gb Mbps)—GMII/MII/TBI/RGMII/RTBI Electrical Characteristics.”

7.3.1 MII Management DC Electrical Characteristics

The MDC and MDIO are defined to operate at a supply voltage of 3.3 V. The DC electrical characteristics

for MDIO and MDC are provided in Table 28.
