In some embodiments, prior to initiating a temperature-calibration session based on one or more above-described trigger conditions, a check may be performed on the temperature-calibration status of XO 106 to ensure that XO 106 is not fully/completely temperature-calibrated or that a pre-specified time has elapsed since XO 106 was last temperature-calibrated. Thus, needless, redundant, or in some cases, conflicting operations can be avoided. Accordingly, in one implementation, a status indication or flag may be provided in XO manager 108 related to temperature-calibration status of XO 106. The status indication may be stored, for example, in a storage means such as a register (not explicitly shown), which may be situated within XO manager 108 or any other suitable storage medium. If XO 106 had been temperature-calibrated, for example, based on one or more trigger conditions, then the temperature-calibration status or temperature-calibration flag would have been updated to indicate the status as “temperature-calibrated.” A subsequent or second trigger, based for example, on a subsequent or second condition related to temperature-calibration of XO 106 will be suppressed or prevented from initiating a temperature-calibration session for XO 106. On the other hand, if the temperature-calibration flag indicates that the temperature-calibration status of XO 106 is “not fully temperature-calibrated,” then a second trigger condition may be detected, and a second temperature-calibration session may be initiated. In another example, the temperature-calibration flag may be accompanied by or replaced with a recorded time of previous temperature-calibration. An aspect of the recorded time of previous temperature-calibration comprises designating a pre-specified time associated with quality of temperature-calibration, such that, if the pre-specified time has elapsed since the recorded time of previous temperature-calibration, XO 106 may be treated as not fully temperature-calibrated. This aspect is based on the characteristic of mechanical structures like XO 106 to degrade in quality over time, and more specifically a characteristic of XO 106 to lose precision of temperature-calibration. Accordingly, upon each successful/complete temperature-calibration of XO 106, the time (e.g. based on any clock, such as clock 104, on device 100) at which temperature-calibration was completed may be recorded or stored in a storage means such as a register or memory. Upon detection of a trigger condition, the recorded time may be consulted, and if the pre-specified time has elapsed, the temperature-calibration status of XO 106 may be designated as not fully temperature-calibrated. The pre-specified time may be based on individual specifications of XO crystals, and may be based on information provided by the manufacturer.
