Abstract
A phase-locked loop circuit including a phase detector having a reference clock input; a charge pump having an input coupled to an output of the phase detector; a non-integrating loop filter having an input coupled to an output of the charge pump; a voltage adder having a first input coupled to an output of the loop filter, a voltage-controlled oscillator (VCO) having an input coupled to an output of the voltage adder; and a first frequency divider having an input coupled to an output of the VCO, and an output coupled to the second input of the phase detector. The circuit further includes frequency control circuitry that has an input coupled to the output of the VCO, a reference clock input, and an output coupled to a second input of the voltage adder.
