Figure 1. Block diagram of a phase-locked loop
A phase-locked loop (PLL) circuit is a feedback system that combines a voltage controlled oscillator (VCO) and a phase detector in such a way that the oscillator signal tracks an applied frequency or phase modulated signal with the correct frequency and phase. PLLs are used when stable, higher output frequencies ne
