Ethernet Management Interface

The electrical characteristics specified in this section 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 2.6, “Ethernet Interface.”

2.7.1

MII Management DC Electrical Characteristics

The MDC and MDIO are defined to operate at a supply voltage of 3.3 V. The following table provides the DC electrical

characteristics for MDIO and MDC.
