Title:
METHOD AND APPARATUS FOR CALIBRATING CRYSTAL OSCILLATOR, TERMINAL DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/249067
Kind Code:
A1
Abstract:
Disclosed in the present application is a method for calibrating a crystal oscillator, comprising: collecting at least two sets of temperature values in a preset time interval and the frequency deviation value of a crystal oscillator at the at least two sets of temperature values, the first time interval being greater than a first threshold; on the basis of the at least two sets of temperature values and the frequency deviation value of the crystal oscillator at the at least two sets of temperature values, determining a first constant; and, on the basis of the first constant, calculating the frequency deviation of the crystal oscillator in order to implement calibration of the frequency deviation. Also disclosed in the present application are an apparatus for calibrating a crystal oscillator, a terminal device, and a storage medium.
