The system may include a local oscillator device. The system may include a phase locked loop (PLL) device coupled to the local oscillator device and a reference clock source. The PLL device may obtain a reference clock signal from the reference clock source to produce an extracted clock signal. The system may include a drift monitoring device coupled to the local oscillator device and the PLL device. The drift monitoring device may determine an amount of oscillator drift within the local oscillator device using the extracted clock signal and an oscillator signal from the local oscillator device. The system may include a drift compensation device coupled to the drift monitoring device and the PLL device. The drift compensation device may transmit a drift compensation signal to the PLL device based on the amount of oscillator drift."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for managing holdover","description":"A system for managing holdover.
