A phase locked loop standard frequency is the value that set up it to a phase locked loop.
TE
This value becomes same a dividing ratio of amplitude modulation with a phase locked loop standard frequency.
L 13942296513
However, a dividing ratio of frequency modulation becomes 2 times of phase locked loop standard frequencies.
