    Abstract: A bus architecture for the application of data transmission between distinct integrated circuits. The bus architecture includes at least one transmission line connecting with I/O pin of ICs for transmitting data. In a middle point of the transmission line, there is a middle resistor with a resistance value preferably equal to the characteristic impedance of the transmission line. In addition, there are internal pull-up resistors within the ICs, which has a first end coupled to the I/O pin and a second end coupled to the voltage source. Each pull-up resistor has a resistance value higher than the characteristic impedance of the transmission line, for example, 2 or 3 times of the characteristic impedance, for suppressing the rising edge ringback.

    Abstract: A noise immunity circuit has a distributed electrical plane to which noise susceptible components are coupled. Also, in a close proximity are noise generating circuits that generate electrical noise onto the distributed electrical plane that affect the noise susceptible components. A coupling means is used to couple the noise susceptible circuits to the distributed electrical plane so that the noise of the distributed electrical plane is common to all points in the noise susceptible circuit. Also, inputs and power to the circuit are coupled to the distributed electrical plane so that the common noise is imposed upon them. Coupling preferably takes place through a variety of capacitors and resistors so that high frequency noise is coupled to the noise susceptible circuit.

    Abstract: A circuit board (1) for use in a connector between cables of a data transmission system has at least one array of input terminals (T1-T8) for incoming signals, at least one array of output terminals (t1-t8) for outgoing signals, and a respective conductive track (5) connecting each input terminal to a respective output terminal. Closed loops (6, 7, 8) of conductive material are connected to at least some of the terminals or conductive tracks, the loops being positioned on the circuit board to reduce crosstalk from the levels which would exist within the connector in the absence of such closed loops. The loops associated with one terminal will be positioned on the board opposite loops associated with another terminal or terminals to produce coupling therebetween. The invention is particularly applicable to RJ45 plug and jack systems.

    Abstract: In the case of a card cage for an electronic control unit having signal-processing analog and/or digital components, high-speed digital components, as well as components having both signal-processing functional parts, as well as high-speed digital functional parts and power components, which are arranged on a multilayer printed-circuit board and are electroconductively connected to a shared ground plane, the signal-processing components of each module having a shared connection to the common ground plane, the radiated interference from the control unit produced by high-frequency interference currents can be reduced, and high current densities in the ground plane and resultant potential shifts can be prevented from adversely affecting the signal processing, in that the signal-processing components are combined into signal-processing modules having at least one shared function, and the ground connections of all components of such a functional module are routed in each case via conductor connections to a common point of connection conductively connected over the shortest path to the shared ground plane, and the high-speed digital and power components are directly linked to the shared ground plane. By introducing an additional voltage-supply plane, the radiated interference from the control unit is able to be further reduced.

    Abstract: In a printed-wiring board, first and second hard substrates each having electronic components mounted thereon are connected through a flexible substrate interposed therebetween. A circuit pattern printed on each of the hard and flexible substrates electrically connects the electronic components mounted on the hard substrates through the flexible substrate. The circuit pattern includes a plurality of parallel-connected signal lines. The parallel-connected signal lines are spatially separated on the flexible substrate, and the both ends of the parallel-connected signal lines are located in the hard substrates, respectively. A single signal line of the circuit pattern branches on one hard substrate into the parallel-connected signal lines, which extend through the flexible substrate and are converged to a single signal line on the other hard substrate.

    Abstract: The device of the invention comprises a bus (B) constituted by a series of lengths each of constant width and each of arbitrary length. The widths of the different lengths vary along the bus from one length to another, with the length connected to an emitter (E) being the widest. Each junction between two lengths is connected by a branch line (L2 to Ln) to an electronic circuit (D2 to Dn). The lines are of arbitrary lengths and have the same characteristic impedance. The end length (B1) of the bus is connected to an electronic circuit (D1). The end length and the branch lines are all terminated on their characteristic impedance. When signals are distributed symmetrically, distribution takes place from a differential emitter via two identical buses which are connected via differential lines to the electronic circuits.
