  • DEVICE AND METHOD FOR LOCKING AND CALIBRATING FREQUENCY
    Publication number: 20110304402
    Abstract: A device and a method for locking and calibrating a frequency is provided for receiving a precise external clock frequency to lock an adjustable oscillator that controls an oscillation frequency to a predetermined frequency. The device comprises a process unit and a frequency adjusting unit. The process unit is provided for comparing the oscillation frequency with a precise frequency to generate a frequency difference and a calibration signal according to the frequency difference. The frequency adjusting unit generates a locking voltage according to the comparison result of the calibration signal and the internal oscillation frequency for locking the oscillation frequency of the external adjustable oscillator to the predetermined frequency, so that the adjustable oscillator still can output a precise oscillation frequency without requiring a precise oscillator.
