Abstract

A VCO phase lock loop system may include a first voltage controlled oscillator that provides a first oscillation signal relative to a first frequency and a second voltage controlled oscillator that provide a second oscillation signal relative to a second frequency. A loop filter capacitor may be associated with both the first voltage controlled oscillator and the second voltage controlled oscillator. A selection device may enable components associated with the either one of the voltage controlled oscillators while disabling components associated with the other one of the voltage controlled oscillators.
