Abstract
Oscillator circuitry and methods of operation thereof are provided in which the oscillator circuitry includes at least a first oscillator, a second oscillator, and a lock detector. The first oscillator is configured to generate a first clock signal. The second oscillator is configured to generate a second clock signal. The lock detector is configured to detect a stable phase lock between the first clock signal and the second clock signal and to switch an output of the oscillator circuitry from the first clock signal to the second clock signal in response to detecting the stable phase lock.
