摘要

A printed wiring board apparatus for a clock signal supply circuit in use with a signal processing circuit is disclosed. Clock pulse generator IC (14) for generating clock signal and load IC (16) are mounted at predetermined locations on printed wiring board. Ground patterns (30, 32) aligned with each other are located between ground terminals (18, 20) of ICs (14, 16). Clock signal supply patterns (38,40) aligned with each other are located between output terminal (24) of IC (14) and input terminal (26) of IC (16). Ground patterns (30, 32) and clock signal supply patterns (38, 40) are spaced from each other. Output terminal (24) of IC (14) and input terminal (26) of IC (16) are also connected by a ground pattern (22). Ferrite choke (46) connects ground patterns (30, 32) with clock signal supply patterns (38, 40) in a mutual inductive manner. Therefore, the clock signal may be supplied from IC (14) to IC (16), with little waveform distortion. <IMAGE>
