Generally, PLL is composed as follow Figure. - PFD (Phase Frequency Detector) PFD compares the phase of the VCO output frequency, with the phase of a reference signal frequency output pulse is generated in proportion to that phase difference. - LF (Loop Filter) LF smooths the output pulse of the phase detector and the resulting DC component is the VCO input. - VCO (Voltage Controlled Oscillator) VCO is controlled by loop filter output. The output of the VCO is fed back to the phase frequency detector input for comparison which in turn controls the VCO oscillating frequency to minimize the phase difference. - FD (Frequency Divider) FD divides too much different frequency that is oscillated from the VCO to compare it with reference signal frequency.
