Interface system of differential current drive system that includes the receiving part transmitting section of the differential current drive system, and the sending unit and the receiving unit of the differential current drive system

摘要

The present invention, the transmission unit of the differential current-driven transmission unit of the differential current driving system to be transmitted to the receiving unit data by adjusting the direction of the current flowing through the transmission line, and the transmission of the differential current-driven I will disclose to interface system of differential current drive system that includes a transmitting unit of the differential current drive system with. Transmission section of the differential current driving method, comprises a current source, a switch block equilibrium current direction and the selected block. The current source sinking current flowing from the transmission line pair, or supplying current to the transmission line pair. By transmitting a current flowing from the current source to the transmission line at one of said transmission line pairs, said current direction selection block is transmitted to the current source the current flowing in the transmission line of the remaining one. Equilibrium switch block is initialized to the equilibrium state the transmission line pair.
