Abstract
A method of calibrating a PLL that includes forcing a control voltage input to a voltage controlled oscillator to be a reference voltage and setting a calibration divider coupled to receive an output clock signal from the voltage controlled oscillator such that the calibration divider utilizes one of a plurality of divisors that results in the output clock signal having a high frequency can substantially avoid overshoot and glitch problems associated with conventional PLL calibrations.
