PLL holdover refers to the mode of operation in a Phase-Locked Loop (PLL) system when it loses its reference signal but continues to generate a stable output frequency using its internal oscillator. During holdover, the PLL maintains frequency accuracy and stability for a limited time based on its design and the quality of its components. This is crucial in applications like telecommunications and navigation, where maintaining a consistent signal is essential even in the absence of a reference. However, the accuracy may gradually drift over time without the reference signal.
