International Classification:

H05K 102

US Classification:

174250, 174255, 257690

Assignee:

Intel Corporation - Santa Clara CA

International Classification:

G06F 1340

US Classification:

710305, 333109, 333124, 333238, 333246, 375257, 375258

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.

International Classification:

H04L 138

US Classification:

375220, 375258, 375259, 375295, 370365, 370403, 370407, 370424, 710106, 710126, 710129

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.

Assignee:

Intel Corporation - Santa Clara CA

International Classification:

H01P 500

US Classification:

333 24R, 333109, 333116

Abstract:

The method of networking comprises connecting a first coupler to a first and second transmission line to couple the first and second transmission lines, connecting a second coupler to the second and a third transmission line to couple the second and third transmission lines, connecting a third coupler to the first and third transmission line to couple the first and third transmission lines, connecting a first end of the first transmission line to a first digital device, connecting a first end of the second transmission line to a second digital device, and connecting a first end of the third transmission line to a third digital device. A signal is transmitted through the first, second, or third transmission line, by one of the digital devices, and is received by at least one digital device different from the transmitting digital device.
