100M MII: Synchronous Transmit Timing
The table below lists the significant time periods for the 100M MII Interface synchronous transmit timing. The time
periods consist of timings of signals on the following pins:
• TXCLK
• TXD[3:0]
• TXEN
• TXER
The 100M MII/100M Stream Interface Synchronous Transmit Timing Diagram figure shows the timing diagram for
the time periods.
