A clock multiplexer (clock MUX) selects one of the several inputs and propagates that signal forward. Renesas offers several types of clock multiplexers that not only include a multiplexing function, but also clock divider and fanout buffer functions integrated on the same device. This not only reduces the total part count in a clock tree, but can also help improve the performance in many cases.
