10.5.20 Auto-Negotiation Fast Link Pulse Timing
Table 10-27 lists the significant time periods for the ICS1893AF Auto-Negotiation Fast Link Pulse. The time
periods consist of timings of signals on the following pins:
• TP_TXP
• TP_TXN
Figure 10-21 shows the timing diagram for one pair of these differential signals, for example TP_TXP minus
TP_TXN.
