22 / 76 page ![]() MPC8306 PowerQUICC II Pro Integrated Communications Processor Family Hardware Specifications, Rev. 0 22 Freescale Semiconductor Ethernet and MII Management Figure 10. Local Bus Signals, GPCM/UPM Signals for LCCR[CLKDIV] = 4 8 Ethernet and MII Management This section provides the AC and DC electrical characteristics for Ethernet interfaces. 8.1 Ethernet Controller (10/100 Mbps)—MII/RMII Electrical Characteristics The electrical characteristics specified here apply to all MII (media independent interface) and RMII (reduced media independent interface), except MDIO (management data input/output) and MDC (management data clock). The MII and RMII are defined for 3.3 V. The electrical characteristics for MDIO and MDC are specified in Section 8.3, “Ethernet Management Interface Electrical Characteristics.” 8.1.1 DC Electrical Characteristics All MII and RMII drivers and receivers comply with the DC parametric attributes specified in Table 19. LCLK UPM Mode Input Signal: LUPWAIT tLBIXKH tLBIVKH tLBIVKH tLBIXKH tLBKHOZ T1 T3 UPM Mode Output Signals: LCS[0:3]/LBS[0:1]/LGPL[0:5] GPCM Mode Output Signals: LCS[0:3]/LWE tLBKHOV tLBKHOV tLBKHOZ T2 T4 Input Signals: LAD[0:15] |
