Abstract
A method for generating parameters for adjusting the frequency of a VCO. A desired carrier frequency may be based off the output of the VCO. The method determines parameters that are operable to adjust the frequency of the VCO, based on the channel number. The channel number may be input into combinatorial logic to determine the parameters. Offsets, which may be scaled, may be added to the channel number before determining the parameters, wherein the frequency of the VCO is further adjusted based on the offset(s). A first parameter may be operable to select a frequency scalar in a circuit with the VCO. A second parameter may be operable to generate a feedback signal for adjusting the frequency of the VCO.
