Ethernet Management Interface Electrical Characteristics
The electrical characteristics specified here apply to the MII management interface signals management
data input/output (MDIO) and management data clock (MDC). The electrical characteristics for GMII,
RGMII, TBI and RTBI are specified in Section 8.1, “Three-Speed Ethernet Controller
(TSEC)—GMII/MII/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 2.5 or 3.3 V. The DC electrical
characteristics for MDIO and MDC are provided in Table 32 and Table 33.
