摘要： The present invention provides a matched-impedance jumper that is operable to connect pairs of differential signal conductors to provide improved signal transmission characteristics. In an embodiment of the invention, the impedance-matched jumper is used to connect a first pair of differential signal conductors to a selected pair of differential signal conductors selected from a plurality of second pairs of differential signal conductors. The impedance-matched jumper comprises a plurality of input pins that are operable to connect with a plurality of connection pads on the first pair of differential signal conductors and a plurality of output pins operable to connect with a plurality of connection pads on the predetermined second pair of differential signal conductors. A plurality of internal conductors are operably connected to the input pins and the output pins to define a signal path therebetween. The signal path defined by the input pins, the output pins, and the internal conductors provides an impedance-matched passthrough for differential signals.

摘要： A method and apparatus for decreasing crosstalk between conductors, particularly differential pairs, that are routed in high-density patterns on printed circuit boards system. In one embodiment of the invention, a single-ended conductor is divided at a first point into two single-ended conductors of equal width, with the two single-ended conductors being routed around and alongside a differential pair of conductors. Equal and opposite noise is coupled onto each branch of the single-ended signal from each side of the differential pair. The two single-ended conductors are rejoined at a second point to form a combined single-ended conductor. Signals traveling along the two separate paths of the single-ended are combined at the second point and noise carried in the respective signals is cancelled. Noise coupled into the differential pair from the two single-ended paths is eliminated at the receiving end as common mode noise. In other embodiments of the present invention, the single-ended conductors and the differential pairs are oriented between two planes in stripline or dual stripline configurations. The method and apparatus of the present invention can be implemented in numerous media, such as vias and cables (including flex and ribbon).
