A system for allowing an asynchronous clock signal to be selected from a plurality of asynchronous clock signals without causing glitches. In the system, a requestor is connected to control signals. The control signals indicate to the requestor which asynchronous clock signal, of the two or more clock signals, to request. The requestor informs a selector of the request. The selector determines which asynchronous clock signal was selected. The selected asynchronous clock is then detected by the detector. The detector feeds the selected asynchronous clock signal to a signal output. The signal output releases the selected asynchronous clock signal.
