JamSynch
Figure D-9 X72 JamSynch State
When the X72 1PPS output is compared to
the X72 1PPS Input, if the difference is
≥ 1 µsec. the state returns to holdover to
collect a second data set
When two consecutive slopes are in range,
the X72’s 1PPS output is synchronized to its
1PPS input.
If the difference is < 1 µsec. the algorithm
waits 6 more pulses and then advances to
the Discipline state
