Abstract
Systems, methodologies, media, and other embodiments associated with making a frequency change through frequency synthesis and digital selection of out-of-phase synthesized signals are described. One exemplary system embodiment includes a locked loop logic (e.g., phase locked, delay locked) that may receive a reference clock signal, process the reference clock signal into signals with different phases, and make those signals available to a selection logic. The exemplary system may also include a state logic that stores frequency divisors that facilitate selecting and tracking output signals provided by the selection logic. The exemplary system may also include a phase logic that stores output signal phase data associated with computing, describing, and/or selecting an output signal.
