For the purpose of achieving multiplexing of data signals for the channels of more than four in number in the generating of a frequency-divided clock signal using toggle flip-flop circuits (TFF), while avoiding any possible phase shift relationship between generated frequency-divided clock signals attributed to the indefinite initial state posing the inherent problem of the TFF, there is provided a clock generator circuit comprising a plurality of toggle flip-flop circuits connected in series, capable of outputting a pair of frequency-divided clock signals with different phases; and a delay circuit connected to the toggle flip-flop circuit, capable of outputting a clock signal with a phase shifted with respect to the phases of the pair of frequency-divided clock signal phases by delaying either one or both of the pair of frequency-divided clock signals being outputted from the toggle flip-flop circuits.
