Auto-Negotiation Fast Link Pulse Timing
The table below lists the significant time periods for the ICS1894-32 Auto-Negotiation Fast Link Pulse. The time
periods consist of timings of signals on the following pins:
TP_TXP
TP_TXN
The Auto-Negotiation Fast Link Pulse Timing Diagram shows the timing diagram for one pair of these differential
signals, for example TP_TXP minus TP_TXN.
