Abstract
A multiplexer circuit for multiplexing several clock signals is controlled by at least one selection signal, and includes for each clock signal a respective delay module producing a delayed clock signal taking the value of the clock signal in response to the appearance of a predetermined switching level of the clock signal while the selection signal is in a first state and no busy signal is then present, and interrupting the delayed clock signal in response to the appearance of the switching level if the selection signal is then in a second state. The busy signal is produced whenever any of the delay module is producing a delayed clock signal, and an output signal is derived from the delayed clock signal.
