Abstract
A frequency synthesizer for producing an output whose phase and/or frequency can be finely adjusted under digital control. The synthesizer utilizes a phase lock loop including a phase detector responsive to a prescale divide-by-N frequency divider and a feedback divide-by-M frequency divider to product an output signal F.sub.OUT. The phase of F.sub.OUT can be shifted by a small increment by slightly adjusting the values of the divisors M and N.
