Abstract
A low power mode control module for a crystal oscillator which performs the following steps: detecting whether an oscillation output signal of the crystal oscillator is output stably; when the oscillation output signal of the crystal oscillator is output stably, comparing at least one of an oscillation input signal and the oscillation output signal with an amplitude control signal to determine whether to adjust the amplitude control signal; when the amplitude control signal does not need to be adjusted, generating an upper bound reference voltage and a lower bound reference voltage associated with the amplitude control signal; and according to whether the oscillation output signal exceeds a reference voltage range of the upper reference voltage and the lower reference voltage, generating a low power mode control output signal associated with a crystal oscillator enable signal for enabling the crystal oscillator.
