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 8.1, “Three-Speed Ethernet Controller

(10/100/1000 Mbps)— GMII/MII/RMII/TBI/RGMII/RTBI Electrical Characteristics.”

8.3.1

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 36.

8.3.2

MII Management AC Electrical Specifications

Table 37 provides the MII management AC timing specifications.
