Pll Diagram. The working of a pll is as follows. There are several different types.
A 5 2 v zener diode is provided for supply regulation if necessary. The pll is a professional lacrosse league with the best players in the world. The figure shows the block diagram of the phase locked loop system in fm transmitter that consists of different blocks such as a crystal oscillator phase detector loop filter voltage controlled oscillator vco and frequency divider.
Indeed today s logic pll will implement most of this interface with the exception of the lock indicator output.
It is basically a flip flop consisting of a phase detector a low pass filter lpf and a voltage controlled oscillator vco. Pll circuits operate by comparing the phase of an external signal to the phase of a clock signal produced by a voltage controlled crystal oscillator vcxo.
