<p>PROBLEM TO BE SOLVED: To provide a clock signal transmission system that reduces spurious electromagnetic radiation noise generated attended with a clock signal and is hardly susceptible to the effect of signals existing in the surrounding. SOLUTION: The clock signal led to many points on a printed circuit board is transmitted by the LVDS(low voltage differential signaling) system. Since a common mode noise is eliminated from the output LVDS signal, the effect of noise in the surrounding is hardly susceptible. Since the LVDS signal is a signal with a small amplitude, a cause for unwanted electromagnetic radiation noises can be avoided and the effect on external devices can be decreased.</p> |
