Ethernet Management Interface Electrical Characteristics
9
The electrical characteristics specified here apply to MII management interface signals ECn_MDIO
(management data input/output) and ECn_MDC (management data clock). The electrical characteristics
for GMII, SGMII, RGMII, RMII, TBI and RTBI are specified in
Three-Speed Ethernet (eTSEC).”
9.1
The ECn_MDC and ECn_MDIO are defined to operate at a supply voltage of 3.3 V or 2.5 V. The DC
electrical characteristics for ECn_MDIO and ECn_MDC are provided in
