Abstract
A system for generating a glitch-free output signal having a frequency. The system comprises a frequency divider for receiving a signal having an input frequency, wherein the frequency divider is configured to generate a plurality of corresponding phase-shifted signals. A retimer is coupled to the frequency divider and is configured to receive the phase-shifted signals and to generate multiplexer input signals for receipt by a multiplexer. The retimer is further configured to receive retimer control signals and to generate corresponding multiplexer control signals. The multiplexer is coupled to the retimer and has input terminals configured to receive the multiplexer input signals. The multiplexer is controlled by the multiplexer control signals so as to alternately and successively provide at its output terminal one of the multiplexer input signals. As the signal level of each phase-shifted signal transitions between a “high” position and a “low” position, the multiplexer control signals are configured to be employed at a time corresponding to the time when a phase-shifted signal experiences a transition.
