摘要： Aspects of the invention may comprise an integrated circuit comprising a memory, a temperature sensor, a crystal, and a communication module. Data stored in the memory may indicate a frequency of the crystal as a function of temperature and/or time. The memory may be writable via the communication module. Data stored in the memory of the integrated circuit may be updated based on an age and/or time of use of the integrated circuit. The time of use may be one or both of: how long the crystal has been oscillating since its most-recent start up, and how long the crystal has been in use over its lifetime. An electronic device may calculate a frequency of an oscillating signal output by the crystal based on a temperature indication from the temperature sensor and data read from the memory of the integrated circuit.

摘要： Aspects of a method and system for using a frequency locked loop LOGEN in oscillator systems may include generating an oscillating signal via one or more circuits comprising a feedback loop. The generation may be controlled by enabling or disabling the feedback loop, based on the generated oscillating signal. The one or more circuits may comprise a frequency-locked loop (FLL) that may enable the generation of the oscillating signal. The frequency-locked loop may comprise a voltage-controlled oscillator. The feedback loop may be disabled when an estimated frequency difference between a reference signal and a feedback signal may be less than or equal to a specified threshold. The feedback loop may be enabled when an estimated frequency difference between a reference signal and a feedback signal may be greater than a particular threshold.

摘要： A global navigation satellite system (GNSS) enabled mobile device may be operable to assert one of autoblank signals when RF interference is detected in received GNSS signals for one of consecutive first time windows. The asserted autoblank signals are monitored by the GNSS enabled mobile device over time intervals corresponding to consecutive second time windows and a rate at which the autoblank signals are asserted for each of the consecutive second time windows is determined by the GNSS enabled mobile device based on the monitoring. The GNSS enabled mobile device may be operable to determine whether to blank processing of the received GNSS signals based on the determined rate. The autoblank signals may be asserted by the GNSS enabled mobile device based on a number of the received GNSS signals whose absolute signal levels exceed a signal level threshold for the first time window.
