Abstract

A device including at least one processor, and an analog-to-digital (ADC) circuit, wherein the at least one processor is configured to generate an excitation signal and provide the excitation signal to a crystal in a pierce oscillation configuration, wherein after providing the excitation signal, the ADC circuit is configured to obtain as input a signal output from the crystal and convert the signal to a digital output; the at least one processor is configured to compare the digital output of the ADC circuit to a plurality of thresholds and based on the comparisons is further configured to drive the crystal to cause the crystal to operate as a pierce oscillator and to generate a clock signal from at least of one of the comparisons.
