Title: Technique for glitchless switching of asynchronous clocks

Abstract: A technique for glitchless switching among different frequency input clocks in a circuit includes monitoring each of the clocks and determining when the relative phases of the respective clocks are within a predetermined maximum of phase difference. Once the relative phases of the respective clocks are within an acceptable range, the system switches from one clock to another.
