Abstract

An apparatus and method for synchronizing a reference oscillator. A frequency of an adjustable frequency reference oscillator is adjusted based on an indication that radio signal processing is inactive and based on a phase error between a synchronized frequency reference signal and a frequency based on a synchronization reference signal. The adjustable frequency reference oscillator provides the synchronized frequency reference signal for a radio frequency circuit and a timing signal indicates whether radio signal processing by a radio frequency circuit is active or inactive. Adjustment of the frequency of the adjustable frequency reference oscillator is inhibited based on the timing signal indicating that radio signal processing is active.
