The main function of a PLL is to lock on to an input logical signal of any given frequency, even when the signals are distorted, or they are coming from a noisy background, & signal is mixed with some other signals having different frequencies. The essential components of a PLL are shown in the diagram below. The first stage is the phase detector. It receives 2 logic-level signals, one at the input to the PLL and the other fed back from its output.
