The PLL consists of a Voltage-Controlled Oscillator (VCO), which is tuned to the desired frequency, and a Phase Detector (PD) which monitors the frequency and compares it to the reference clock. When the frequency of the VCO differs from the reference, the PD adjusts the voltage applied to the VCO until the two frequencies match. This regulation process ensures that the output frequency is stable.
