Abstract: PROBLEM TO BE SOLVED: To provide a waveform shaping circuit which can secure a setup time and a hold time, prescribing the timing between a system clock and a reference clock, at the same time for all channels irrelevantly to the environment of the channels. SOLUTION: A frequency dividing circuit 120 divides the frequency of the reference clock F0 to generate clocks F1 and F1n which are opposite in phase from each other.
