phase-locked loop
Signal tracking circuit
A phase-locked loop is an electronic circuit that synchronizes its output signal with an input signal by continuously adjusting to match frequency and phase.
Abbreviated PLL.
These circuits are fundamental to radio receivers, telecommunications, and clock generation in computers—anywhere a stable, synchronized frequency matters: The chip uses a phase-locked loop to recover the clock signal from incoming data.
