42 / 139 page ![]() MPC8568E/MPC8567E PowerQUICC III Integrated Processor Hardware Specifications, Rev. 1 42 Freescale Semiconductor Ethernet Interface and MII Management 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 37. 8.3.2 MII Management AC Electrical Characteristics Table 38 provides the MII management AC timing specifications. Table 37. MII Management DC Electrical Characteristics Parameters 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 Input high current (OVDD= Max, VIN 1= 2.1 V) IIH —40 μA Input low current (OVDD= Max, VIN 1= 0.5 V) IIL –600 — μA Note: 1. The symbol VIN, in this case, represents the OVIN symbols referenced in Table 2 and Table 3. Table 38. MII management AC timing specifications Parameters Symbol Min Max Unit Notes MDC frequency fMDC —2.5 MHz 2 |
