Abstract
Methods, systems, and apparatus, for enhanced clock frequency control. In some implementations, a clock system tracks time using a clock signal having a clock frequency. An interface receives a time reference from a reference clock, and a feedback loop synchronizes the clock system with the reference clock. The feedback loop includes a feedback loop controller configured to determine a clock frequency adjustment for the clock system based on an offset between the time reference and a time indicated by the clock system. The feedback loop also includes a smoothing filter configured to alter the clock frequency adjustment determined using the feedback loop controller. The feedback loop updates the clock frequency of the clock system based on the altered clock frequency adjustment.
