DEVICE AND METHOD FOR RETIMING AN OSCILLATION FREQUENCY OF A VCTCXO OSCILLATOR

A device (110), comprising a temperature sensor (111) accesses an external time or frequency reference (121; 130) for adjusting an oscillation frequency of a VCTCXO oscillator (113). The device determines a variation in the VCTCXO oscillator's ambient temperature over a predetermined time range...

Beschreibung
Zusammenfassung:	A device (110), comprising a temperature sensor (111) accesses an external time or frequency reference (121; 130) for adjusting an oscillation frequency of a VCTCXO oscillator (113). The device determines a variation in the VCTCXO oscillator's ambient temperature over a predetermined time range thanks to measurements from the temperature sensor, and adjusts a frequency, or rate, of access to the external time or frequency reference in order to obtain time or respectively frequency information for adjusting the oscillation frequency of the VCTCXO oscillator, according to the determined variation in temperature.
