  • Method for configuring multiple-output phase-locked loop frequency synthesizer
    Patent number: 7132864
    Abstract: A method is provided to configure a multiple-output phase-locked loop frequency synthesizer based upon a desired set of output frequencies. The method includes an act of selecting a candidate output frequency(s) for the synthesizer's VCO and corresponding configurations for the output dividers. Based upon the candidate output frequency(s) and corresponding output divider configurations, the method provides another act of selecting a suitable feedback signal and input and feedback divider configurations. The resulting various potential configurations for the frequency synthesizer are tested based upon predetermined suitable criteria to provide a selected frequency synthesizer configuration.
