Abstract
The invention relates to an interfacing device for pseudo-differential transmission through interconnections used for sending a plurality of electrical signals. The interfacing device of the invention includes signal terminals and a common terminal distinct from the reference terminal (ground). A transmitting circuit receiving the input signals of the transmitting circuit coming from a source delivers, when the transmitting circuit is in the activated state, currents to the signal terminals. A receiving circuit delivers, when the receiving circuit is in the activated state, output signals of the receiving circuit determined each by the voltage between one of the signal terminals and the common terminal, to the destination. A termination circuit is such that, when it is in the activated state, it is approximately equivalent, for the signal terminals and the common terminal, to a network consisting of 4 branches, each branch being connected to the common terminal and to one of the signal terminals.
