Abstract
Official abstract text for this publication.
Methods, apparatuses, systems and computer-readable media for addressing the aging of oscillation (XO) crystals are presented. Some embodiments may determine a change of age of the XO crystal since last prior use of the XO crystal. Embodiments may then determine that at least one calibration parameter is not suitable for use in at least one calibration technique of the XO crystal, based on the change of age of the XO crystal. Embodiments may then determine at least one fresh calibration parameter configured to update the at least one calibration parameter for suitable use in the at least one calibration technique of the XO crystal.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for calibrating an XO crystal, the method comprising: determining a change of age of the XO crystal since last prior use of the XO crystal; determining that at least one calibration parameter is not suitable for use in at least one calibration technique of the XO crystal, based on the change of age of the XO crystal; expanding a search window of the at least one calibration technique; and determining at least one fresh calibration parameter us…
