Abstract
A method includes locking onto a spread spectrum clock signal to minimize a phase error between an output clock signal and the spread spectrum clock signal. The spread spectrum clock signal has a time-varying frequency that cycles at a modulation frequency. The method includes minimizing a phase angle between spectral components of the output and spread spectrum clock signals near the modulation frequency. In some embodiments, the method may be performed by a phase locked loop.
