27 / 139 page ![]() MPC8568E/MPC8567E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 1 Freescale Semiconductor 27 Ethernet Interface and MII Management Specification Version 1.2 (3/20/1998). The electrical characteristics for MDIO and MDC are specified in Section 8, “Ethernet Interface and MII Management.” 8.1.1 Ethernet Interface DC Electrical Characteristics All GMII, MII, TBI, RGMII, RMII and RTBI drivers and receivers comply with the DC parametric attributes specified in Table 23 and Table 24. The potential applied to the input of a GMII, MII, TBI, RGMII, RMII or RTBI receiver may exceed the potential of the receiver’s power supply (that is, a GMII driver powered from a 3.6-V supply driving VOH into a GMII receiver powered from a 2.5-V supply). Tolerance for dissimilar GMII driver and receiver supply potentials is implicit in these specifications. The RGMII and RTBI signals are based on a 2.5-V CMOS interface voltage as defined by JEDEC EIA/JESD8-5. Table 23. GMII, MII, RMII, and TBI DC Electrical Characteristics Parameter Symbol Min Max Unit Notes Supply voltage 3.3 V LVDD TVDD 3.135 3.465 V 1, 2 Output high voltage (LVDD/TVDD = Min, IOH = –4.0 mA) VOH 2.40 LVDD/TVDD + 0.3 V — Output low voltage (LVDD/TVDD = Min, IOL = 4.0 mA) VOL GND 0.50 V — Input high voltage VIH 2.0 LVDD/TVDD + 0.3 V — Input low voltage VIL –0.3 0.90 V — |
