Abstract
A system and method are presented for multiplexing two or more clocking signals. In one embodiment, a first enable circuit is provided that receives a select signal, a first clocking signal, and an enable signal from a second enable circuit. The first enable circuit generates an enable signal in response to these signals. For example, the first enable circuit could include a flip-flop clocked by the first clocking signal that generates the enable signal when the first clocking signal has been selected (based on the select signal), when the enable signal from the second enable circuit is deasserted and the first clocking signal has reached a falling edge. The enable signal can then be used to filter the first clocking signal (e.g., using an AND gate) to provide the first clocking signal as an output signal. Using the system and method of the present invention, glitches and spikes seen when multiplexing two or more clocking signals can be avoided.
