摘要： Methods and apparatus are provided in the present invention to adjust the frequency of an output clock close to within a required accuracy of an oscillation frequency. In another embodiment, a method comprises: entering a calibration mode; generating a first control word to control a timing of a clock synthesizer; adjusting the first control word until the timing of the clock synthesizer is sufficiently accurate with respect to a timing of a reference clock; sensing a temperature using a temperature sensor; storing a present value of an output of the temperature sensor and the first control word into a non-volatile memory; exiting the calibration mode; entering a normal operation mode; sensing the temperature using the temperature sensor; generating a second control word to control the timing of the clock synthesizer in accordance with an output of the non-volatile memory and the output of the temperature sensor.
