Phase-Locked Loop
The Phase-Locked Loop (PLL) is a closed-loop frequency-control system that compares the phase difference between the input signal and the output signal of a voltage-controlled oscillator (VCO). The negative feedback loop of the system forces the PLL to be phase-locked.
PLLs are widely used in telecommunications, computers, and other electronic applications. You can use the PLL to generate stable frequencies, recover signals from a noisy communication channel, or distribute clock signals throughout your design.
