Chapter 9 DC and AC Operating Conditions
9.5.9 10M Media Independent Interface: Transmit Latency
Table 9-16 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 9-10 shows the timing diagram for the time periods.
