  • Patent number: 7531749
    Abstract: A cable for high speed data communications and method of manufacturing the cable, the cable including a first inner conductor enclosed by a first dielectric layer and a second inner conductor enclosed by a second dielectric layer, the inner conductors and the dielectric layers twisted in a rotational direction at a periodic rate along and about a longitudinal axis and conductive shield material wrapped in the rotational direction at the periodic rate along and about the longitudinal axis around the inner conductors and the dielectric layers, including overlapped wraps at the periodic rate along and about the longitudinal axis. Transmitting signals on the cable including transmitting a balanced signal characterized by a frequency in the range of 7-9 gigahertz on the cable.

  • Publication number: 20080318455
    Abstract: Embodiments of the present invention address deficiencies of the art in respect to backplane connectivity and provide a backplane connector for high density broadside differential signaling. In an embodiment of the invention, a backplane connector can be provided. The backplane connector can include a signal header assembly and a signal receptacle assembly. The signal header assembly can include pairs of differential signaling conductors arranged in columns for broadside signaling. Comparably, the signal receptacle assembly can include pairs of conductor receptacles arranged in columns to receive corresponding ones of the pairs of the differential signaling conductors.

  • Patent number: 5432916
    Abstract: The invention is related to hot plugging of an electrical circuit (1) into a separate non-quiesced signal net (6) in an active system (7), such as a digital or analog bus. The inventive solution proposes the addition of a preconditioning network (4) to precondition the electrical circuit (1) to be hot plugged by partially precharging the parasitic input capacitances (C.sub.c, C.sub.e, C.sub.m) of the electrical circuit (1) before hot plugging. The precharging of the parasitic input capacitances serves to minimize transient effects on the active system (7).

  • Patent number: 5220211
    Abstract: A high-speed data transport system for use in computers, switches, microprocessors or the like includes a low impedance differential bus and a plurality of transceivers connected to the bus. Each of the transceivers is provided with a driver circuit which places data onto the bus and a receiver for accepting data from the bus. The driver includes a pseudo-differential current driving circuit arrangement which sinks current from only one side of the bus while the other side of the differential bus is undisturbed. The receiver includes a differential comparator biased to a preferred output voltage level.
