Abstract: 본 발명은 고속 차동신호용 신호경로를 갖는 회로기판(PCB)에서의 차동신호(Differential Signal)를 왜곡이 없이 외부로 제공하거나 외부로부터의 신호를 회로기판으로 제공하기 위한 차동 쌍 접속 장치에 관한 것이다. 회로기판(PCB)에서의 차동신호는 소정의 입출력 포트를 통해 외부로 제공된다. 종래에는 입출력 포트가 단일모드 신호선(Single-ended Line)에 연결되면 차동신호선의 소정 영역에서 임피던스 부 정합이 일어나 차동신호의 장점을 상실하게 된다. 본 발명의 차동 쌍 접속 장치는 독립된 두 개의 물리적 채널을 제공하며 임피던스 부 정합이 발생되지 않는다.
