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
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 35.
8.3.2
MII Management AC Electrical Specifications
Table 36 provides the MII management AC timing specifications.
