Abstract

See full text

Systems and methods for controlling clock drift of an integrated circuit device are provided. Such a system may include a local oscillator to provide a reference clock signal, a phase-locked loop to provide a system clock signal based on the reference clock signal and a drift control signal, and processing circuitry to generate the drift control signal. In a synchronization mode, the processing circuitry may generate the drift control signal based on an input time reference signal. In a holdover mode, the processing circuitry may generate the drift control signal based on a trained machine learning model.
