Abstract
A semiconductor device comprises synthesized frequency generation logic arranged to receive a reference signal, and to provide an output frequency signal. The synthesized frequency generation logic comprises divider logic arranged to receive the reference signal and to generate a divided signal comprising a frequency with a period equal to N times that of the reference signal. The synthesized frequency generation logic is further arranged to generate the synthesized frequency signal comprising a frequency with a period equal to 1/M that of the divided signal. The synthesized frequency generation logic comprises or is operably coupled to decision logic module and comprises or is operably coupled to a switching logic module such that the decision logic module is arranged to determine whether a near-integer spur arises in using the synthesized frequency signal, and configures the switching logic module to select the synthesized frequency signal in response thereto.
