Diode switch (SWx) 0 = diode no (It becomes LOW input in the case that it is static)
(It becomes HIGH input in the case that it is static)
There is 1 = diode
X = transistor switch
(0 = OFF / 1 = ON)

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