Abstract
The invention relates to a method and a device for transmission through interconnections used for sending a plurality of electrical signals. An interconnection having 4 transmission conductors and a reference conductor cannot be modeled as a uniform multiconductor transmission line. Each end of the interconnection is connected to a termination circuit. The transmitting circuits receive at their inputs the signals from the 4 channels of the two sources, and are connected to 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 interconnection, each receiving circuit being such that the signals of 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 and internal crosstalk.
