Everything about Phase-locked loop
Electronic control system
A phase-locked loop (PLL) is a control system that generates an output signal whose phase is fixed relative to the phase of an input signal. Keeping the input and output phase in lockstep also implies a constant relationship between input and output frequencies. By incorporating a frequency divider, a PLL can generate a stable frequency that is a multiple of the input frequency. Wikipedia →
