Crosstalk-resistant interface circuit for superspeed communication and socket including the interface circuit

The utility model discloses a crosstalk-resistant interface circuit for superspeed communication, including a plurality of pins electrically connected with an RJ45 plug, a plurality of IDC terminals electrically connected with an output cable, and a printed circuit board electrically connecting the pins with the terminals. A transmission line formed by a plurality of transmission branches is formed among the plurality of pins, the plurality of IDC terminals, and the printed circuit board, the plurality of pins allow that the adjacent transmission branches except the first and last transmission branches in the transmission line are provided with pin compensation capacitors. By means of the special space position layout of the pins and the special line layout of the printed circuit board, capacitance is generated between lines to balance the signal interference from the eight lines of an RJ45 plug jack and an IDC wiring base, thereby achieving the aim of signal transmission at a high frequency of 500MHz. The utility model further discloses a socket including the interface circuit.
