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
(10/100/1000 Mbps)— GMII/MII/RMII/TBI/RGMII/RTBI Electrical Characteristics.”
8.3.1
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
