Abstract
An oscillator module used with a plurality of power sources includes an oscillator unit, a clock monitor unit (CMU), a software module and a digital calibration circuit. The oscillator unit generates a clock signal. The CMU is coupled to the oscillator unit, determines whether an amplitude of the clock signal exceeds a predetermined threshold, and outputs an alarm signal if the amplitude of the clock signal is lower than the predetermined threshold. The software module is coupled to the CMU, and receives the alarm signal to output a calibration signal. The digital calibration circuit is coupled to the oscillator and the software module, and outputs a control signal in response to the clock signal and the calibration signal, adjusting the plurality of power sources to modify the clock signal.
