Abstract: The present invention provides a mechanism for supporting high digital bandwidth in a multi-drop bus system. A first device of the system is electrically coupled to a bus. Multiple receiving devices are coupled to the bus through associated electromagnetic couplers having coupling coefficients in a specified range. The geometries of the electromagnetic couplers are selected to reduce variations in the coupling coefficients with changes in the relative positions of the coupler components.

Abstract: The present invention provides a chipset for transferring data through an electromagnetically coupled bus system. The chipset includes a modulator, a matching circuit and a demodulator. The modulator modifies a clock to encode multiple bits in a complementary pair of symbols. The matching circuit modifies the clock signal to generate a complementary pair of reference signals that is transmitted with the complementary symbol pair, and the demodulator decodes a second set of bits from selected properties of a complementary pair of transferred symbols.

Abstract: The present invention provides a mechanism for supporting high digital bandwidth in a multi-drop bus system. A first device of the system encodes multiple bits in a symbol and drives the encoded symbol onto the multi-drop bus. Multiple receiving devices are linked to the bus through electromagnetic couplers. A receiving device samples the encoded symbol through the electromagnetic coupler and recovers the encoded bits from the sampled symbol.

Abstract: A high-speed digital distribution system is presented that includes a transmission line bus that carries modulated digital signals and reference signals. The transmission line bus has a first end electrically connected to a bus interface that modulates digital data onto said transmission line bus and demodulates modulated digital data signals that it receives from the transmission line bus.
