31 / 88 page  MPC8555E PowerQUICC™ III Integrated Communications Processor Hardware Specifications, Rev. 4 Freescale Semiconductor 31 Ethernet: Three-Speed, MII Management Figure 13 shows the RBMII and RTBI AC timing and multiplexing diagrams. Figure 13. RGMII and RTBI AC Timing and Multiplexing Diagrams 8.3 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 are specified in Section 8.1, “Three-Speed Ethernet Controller (TSEC) (10/100/1000 Mbps)—GMII/MII/TBI/RGMII/RTBI Electrical Characteristics.” 8.3.1 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. Table 27.
