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
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 27.
7.3.2 MII Management AC Electrical Specifications
Table 28 provides the MII management AC timing specifications.
