10Base-T: Jabber Timing
The table below lists the significant time periods for the 10Base-T jabber. The time periods consist of timings of
signals on the following pins:
• TXEN
• TP_TX (that is, TP_TXP and TP_TXN)
• COL
The 10Base-T Jabber Timing Diagram shows the timing diagram for the time periods.
Note: For more information on 10Base-T jabber operations, see the section, “10Base-T Operation: Jabber”.
