4.3.1. PLL
The PLL is composed of a Phase Comparator, a Voltage
Controlled Oscillator VCO, a Frequency Divider and an inter-
nal bypass. The Phase Comparator compares the input fre-
quency f
Divider, f
to the phase difference of the two input frequencies. V
trols the VCO which outputs the desired frequency. This fre-
quency is fed back by the Frequency Divider to the Phase
Comparator. The Frequency Divider divides the input fre-
quency down to f
The phase-locked state of the PLL is signaled by a lock sig-
nal. It is available as flag PLLC.LCK. It may be routed to the
