Abstract
A phase-locked loop circuit for use in locking onto a sub-harmonic of the frequency of a reference source. An oscillator operating at the sub-harmonic frequency is injection-synchronized to the primary voltage controlled oscillator of the phase-locked loop, thereby causing it to function as a divider. The injection-synchronized oscillator can be controlled by a loop control signal generated by the loop's phase detector and loop filter.
