Abstract
A method for controlling a frequency output of a phase locked loop (PLL) is provided. The method includes providing digital control words to the PLL to discretely change at least one dividing factor within the PLL. The method further includes applying a time-varying control voltage to a voltage controlled oscillator. The method still further includes applying an output of the voltage controlled oscillator to the PLL as a reference frequency. The method further includes outputting a signal from the PLL, the signal varied in frequency based on one or more of the time-varying control voltage and the at least one dividing factor.
