摘要： A signal generator circuit includes a controller adapted to generate a divide value in accordance with at least a first control signal, and a divider adapted to divide an output signal of the signal generator circuit by the divisor value. The controller is selectively operable in at least one of a plurality of modes in accordance with at least a second control signal. The controller is configured to calculate each of one or more new divide values so as to vary a frequency of the output signal in accordance with at least one of the first and second control signals. The controller is configured to switch between operational modes and/or switch between divide values, the switching between operational modes and/or divide values being performed in such a manner so as to substantially eliminate discontinuities in the frequency of the output signal.
