39 / 144 page  MPC8548E PowerQUICC™ III Integrated Processor Hardware Specifications, Rev. 6 Freescale Semiconductor 39 Ethernet Management Interface Electrical Characteristics Figure 19 provides the AC test load for eTSEC. Figure 19. eTSEC AC Test Load Figure 20 shows the RMII receive AC timing diagram. Figure 20. RMII Receive AC Timing Diagram 9 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, RMII, TBI, and RTBI are specified in “Section 8, “Enhanced Three-Speed Ethernet (eTSEC).” 9.1 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 36. Table 36. MII Management DC Electrical Characteristics Parameter Symbol Min Max Unit Supply voltage (3.3 V) OVDD 3.13 3.47 V Output high voltage (OVDD = Min, IOH = –1.0 mA) VOH 2.10 OVDD + 0.3 V Output low voltage (OVDD =Min, IOL = 1.0 mA) VOL GND 0.50 V Input high voltage VIH 2.0 — V Input low voltage VIL —0.90 V Output Z0 = 50 Ω LVDD/2 RL = 50 Ω TSEC n_TX_CLK RXD[1:0] tRMRDX tRMR tRMRH tRMRR tRMRF CRS_DV RX_ER tRMRDV Valid Data |
