PH_MON_EN
This bit determines whether the input clock whose edge respect to the reference clock is outside ±5% is enabled to be
selected for T0 DPLL.
0: Disabled. (default)
1: Enabled.
Reserved.
This bit is valid only when the PH_MON_PBO_EN bit (b4, 78H) is ‘1’. It determines whether the Phase Transient Monitor
is enabled to monitor the phase-time changes on the T0 selected input clock.
0: Disabled. (default)
1: Enabled.
This bit determines whether a PBO event is triggered when the phase-time changes on the T0 selected input clock are
greater than a programmable limit over an interval of less than 0.1 seconds with the PH_MON_EN bit being ‘1’. The limit
is programmed by the PH_TR_MON_LIMT[3:0] bits (b3~0, 78H).
0: Disabled. (default)
1: Enabled.
These bits represent an unsigned integer. The Phase Transient Monitor limit in ns can be calculated as follows:
Limit (ns) = (PH_TR_MON_LIMT[3:0] + 7) X 156.
