Abstract
Phase locked loop calibration system. Apparatus is provided for calibration of a phase-locked loop. The apparatus includes logic to calibrate an integration filter of the phase-locked loop, and logic to calibrate a charge pump current of the phase-locked loop, wherein the integration filter and charge pump current are calibrated to achieve a desired phase-locked loop performance level.
