摘要： A cable with connector includes a cable including at least two or more differential signal transmission cables for transmitting/receiving differential signals, a connector at both ends of the cable and including a built-in paddle card to electrically connect the differential signal transmission cables to a connected device. The paddle card includes a sending-side transmission path that is formed on the paddle card so as to transmit electrical signals input from the device to the differential signal transmission cables. The sending-side transmission path includes a common-mode reflecting transmission path that is in a common-mode impedance mismatched to a transmission path of the device so as to reflect common-mode signals input from the transmission path of the device.

摘要： A cable with connectors includes a differential transmission path disposed in a paddle card and configured to allow transmission of differential signals between a device and differential signal transmission cables; a chip component mounted on the differential transmission path; and a plurality of foot pads disposed on the differential transmission path to allow mounting of the chip component, the foot pads being greater in width than traces forming the differential transmission path. The differential transmission path has a high-impedance portion at a connection thereof to the foot pads. The high-impedance portion has a differential impedance higher than that of the differential transmission path excluding the high-impedance portion.
