ABSTRACT:
Provided is a system adopting a differential signaling system including a low frequency signaling line arranged to be adjacent to a pair of differential signaling lines in parallel to each other, for transmitting a signal having a frequency which is smaller than a frequency of a signal to be transmitted through the pair of differential signaling lines, in which a transmission end of the low frequency signaling line is connected to a ground pattern through a first capacitive element, and a reception end of the low frequency signaling line is connected to the ground pattern through a second capacitive element. Thus, it is possible to provide, easily and at a low cost, a differential signaling system in which a common mode noise is eliminated without increasing the number of pins.
