Abstract  Abstract

frequency synthesizer for digital telephone system comprising: a first phase-locked loop frequency according to the first reference signal and a second reference frequency signal are combined to produce the frequency output signal within a first predetermined range a second phase-locked loop. It is based on the first signal from the PROM and the third reference frequency signal synthesis to generate a third reference frequency signal a frequency divider and a PROM connected to the second frequency dividing phase-locked loop output signal and provide a second reference signal to the first phase-locked loop.
