Chapter 9 DC and AC Operating Conditions
9.5.11 10M Media Independent Interface: Transmit Latency
Table 9-18 lists the significant time periods for the 10M MII transmit latency. The time periods consist of
timings of signals on the following pins:
⢠TXEN
⢠TXCLK
⢠TXD (that is, TXD[3:0])
⢠TP_TX (that is, TP_TXP and TP_TXN)
Figure 9-12 shows the timing diagram for the time periods.
