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)
7.3.1
MII Management DC Electrical Characteristics
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 Table 21 and Table 22.
