PHASE_MON_PBO_CNFG - Phase Transient Monitor & PBO Configuration
Address:78H
Type: Read / Write
Default Value: 0X000110
Bit
Name
Description
7
IN_NOISE_WINDOW
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.
6-
Reserved.
5PH_MON_EN
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.
4
PH_MON_PBO_EN
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.
3 - 0
PH_TR_MON_LIMT[3:0]
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.
