METHODS AND APPARATUS FOR DYNAMIC FREQUENCY SCALING OF PHASELOCKED LOOPS FOR MICROPROCESSORS

摘要

A phase-locked loop employing a plurality of oscillator complexes is disc losed. The phase-locked loop includes a clock output and a plurality of osci llator complexes operable to generate output signals. The phase-locked loop further includes control logic which is configured to selectively couple an output signal of one of the plurality of oscillator complexes to the clock o utput.
