<p>PURPOSE:To provide a pulse supply device capable of outputting a clock signal to be supplied to a time division multiplexer without distortion even when a switching device switches a connection terminal by making the mutual phase difference between clock signals generated at the output terminals of a clock generators zero. CONSTITUTION:This pulse supply device is provided with plural clock generators A and B which are provided with a means generating the clock signal CK of necessary period based on the master clock signal MK of the necessary period and the n-ary counters of frequency dividers A2 and B2 frequency- dividing the clock signal CK into 1/n (where (n) is integral) so as to output the clock signal generated by one clock generator selected from these clock generators A and B outside. Then, the pulse supply device is provided with a means generating a pulse signal for resetting the counter of another clock generator whenever the selected clock generator counts a prescribed counting value before counting (n) and a means delaying the pulse signal so as to make the mutual phase difference between the clock signals generated by the respective clock generators A and B zero.</p> |
