Abstract
The invention relates to a method and a device for pseudo-differential transmission in interconnections used for sending a plurality of electrical signals. The ends of an interconnection having 4 transmission conductors and a return conductor distinct from the reference conductor are each connected to a termination circuit. Three damping circuits are connected between the return conductor and the reference conductor. The transmitting circuits receive at their inputs the signals from the 4 channels of the two sources, and are connected to the conductors of the interconnection. A transmitting circuit in the activated state produces modal electrical variables, each modal electrical variable being allocated to one and only one channel. The receiving circuits are connected to the conductors of the interconnection, each receiving circuit being such that the 4 channels of a source connected to a transmitting circuit in the activated state are sent to the four channels of the destinations, without noticeable echo, internal crosstalk and external crosstalk.
