Electronic device for an integrated input/output circuit which combines a current switching circuit with a bus cabling system

摘要

The electronic device includes: - a transmission line (1); - a termination circuit (2) adapted for the transmission line (1); - an current switching circuit (3) designed to send onto a bus cabling system a complementary signal. The current switching circuit includes the transmission line (1) and the end of the termination circuit (2); - a connection card including the transmission line (1) and the end of the termination circuit (2), and; - a first integrated circuit chip including the current switching circuit mounted on the connection card. The transmission line (1) possesses a structure in which a line having a characteristic impedance equal to 25 ohms or less and possessing a matched opposed pair wire structures cabled so that the matched opposed pair wires (4) are parallel and have the same length.
