Abstract

PURPOSE:To supply a clock signal with less distortion by providing a ferrite choke to a clock signal supply line and a ground line connected between a clock signal generating circuit and a load circuit. CONSTITUTION:A clock pulse generator IC1 and a load side IC2 are arranged on a printed wiring board and ground terminals 1b, 2b of the IC1, 2 are connected to a common ground pattern 3. Then the clock signal line by the clock supply pattern 4 and the ground line by the ground pattern 6 are penetrated as a pair through the ferrite choke 5. That is, the signal current flowing to the clock signal supply line and the feedback current flowing to the ground line are subject to mutual induction by the ferrite choke 5 to decrease the high frequency impedance. Thus, the waveform distortion of the clock signal supplied to the load circuit is eliminated.
