The frequency divider provides an output frequency as a fraction of the oscillation frequency. The comparator compares the output and reference frequencies and provides a comparison signal when the output frequency is not substantially equal to the reference frequency. The reactance modulator determines and provides to the coefficient register a first plurality of coefficients to control switching of a first subset of the reactance modules to increase the reactance of the oscillator when the output frequency is greater than the reference frequency, and a second plurality of coefficients to control switching of a second subset of the reactance modules to decrease the reactance of the oscillator when the output frequency is less than the reference frequency.
