Preliminary
PLL CONTROL
Introduction
PLL (Phase Lock Loop) is feedback controlled circuit that maintains a constant phase difference between a
reference signal and an oscillator output signal.
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.
