9.5.15 100M MII / 100M Stream Interface: Receive Latency
Table 9-22 lists the significant time periods for the 100M MII / 100M Stream Interface receive latency. The
time periods consist of timings of signals on the following pins:
• TP_RX (that is, TP_RXP and TP_RXN)
• RXCLK
• RXD (that is, RXD[3:0])
Figure 9-16 shows the timing diagram for the time periods.
