Pin
resynchronizes to its input clock as it relocks. If the target VCO frequency
is below this nominal frequency, then the output frequency starts at a
higher value then desired as it locks.
The pfdena signals control the PFD output with a programmable gate. If
you disable the PFD, the VCO operates at its last set value of control
voltage and frequency with some long-term drift to a lower frequency.
The system continues running when the PLL goes out of lock or the input
clock disables. By maintaining the last locked frequency, the system has
time to store its current settings before shutting down.
If the PLL loses lock for any reason (for example, because of excessive
inclk jitter, clock switchover, PLL reconfiguration, or power supply
noise), the PLL must be reset with the areset signal to guarantee correct
phase relationship between the PLL output clocks. If the phase
relationship between the input clock and the output clock and between
different output clocks from the PLL is not important in your design, it is
not necessary to reset the PLL.
