Abstract
A method and apparatus for clock signal noise shaping are described. Embodiments of a clock circuit include a filter coupled to receive an input clock signal and to provide an output clock signal. The filter filters noise of the input clock signal to shape the noise to provide the output clock signal. In a method for adjustment of phase noise, input clock signaling having the phase noise is obtained, and the input clock signal is filtered to adjust the phase noise to provide output clock signaling.
