9.5.22 Auto-Negotiation Fast Link Pulse Timing
Table 9-29 lists the significant time periods for the ICS1893BY-10 Auto-Negotiation Fast Link Pulse. The
time periods consist of timings of signals on the following pins:
• TP_TXP
• TP_TXN
Figure 9-23 shows the timing diagram for one pair of these differential signals, for example TP_TXP minus
TP_TXN.
