A first frequency dividing circuit receives an input clock signal from an input terminal and divides the frequency of the input clock signal to produce a first signal which it supplies to an output terminal. A second frequency dividing circuit divides the frequency of the input clock signal to produce a second signal having the same frequency as the first signal but differing from the first signal in phase. The second signal controls a gating circuit. When switched on, the gating circuit connects the output terminal to the input terminal, or to an auxiliary power-supply or ground terminal, thereby deskewing the signal at the output terminal.
