Abstract

A clock-switching circuit having at least two inputs for receiving at least two different clock sources, an output for providing a selected one of the clock sources, and a switch for selecting the one of the inputs to provide on the output, the switch including elements that, prevent the providing of a truncated version of any of the clock sources on the output, always provide a clock signal on the output, and always maintain phase alignment and pulse ratio of the clock sources on the output.
