10Base-T: Heartbeat Timing (SQE)
Table 10-25
lists the significant time periods for the 10Base-T heartbeat (that is, the Signal Quality Error,
which consists of timings of signals on the TXEN, TXCLK, and COL pins).
Figure 10-18
shows the timing
diagram for the time periods.
Note:
1.
For more information on 10Base-T SQE operations, see
Section 7.5.10, “10Base-T Operation: SQE
Test”
.
In 10Base-T mode, one bit time = 100 ns.
