Abstract
An atomic clock is provided. An output of a tunable LO is coupled to a user output of the atomic clock. A charge pump adjusts the tunable LO with a LO tuning voltage. A follower circuit sets an output frequency of the atomic clock to a frequency of an external reference signal coupled to an external reference input. An atom referenced circuit sets the output frequency of the atomic clock to a frequency based on stored operating settings. A controller stores then current operating settings generated based on a then current external reference signal coupled to the external reference input. The controller is further configured to apply the stored then current operating settings to the atom referenced circuit when the then current external reference signal is removed from the external reference input to maintain the output frequency of the atomic clock at the output frequency set by the follower circuit.
