Ethernet Management Interface Electrical Characteristics
9
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, RMII, TBI, and RTBI are specified in
(eTSEC), MII Management.”
9.1
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
