Abstract

A connector with controlled impedance includes at least one set of differential signal terminals with an associated ground terminal. The ground terminal has a symmetric configuration, while the two differential signal terminals have asymmetric configurations. The asymmetric configurations permit capacitive coupling to occur primarily between the two differential signals in an area of the connector where the inductance of the connector would be high. The two differential signal terminals flank the ground terminal.

Description

technical field

[0001] This invention relates generally to connectors, and more particularly to connectors having improved impedance characteristics and for use in connecting signal cables to printed circuit boards. Background technique

[0002] Many electronic devices rely on transmission lines for transmitting signals between associated devices of a computer or between peripheral devices and circuit boards. These transmission lines consist of signal cables that enable high-speed data transmission.

[0003] These signal cables may use what is known as one or more twisted pairs twisted together along the length of the cable, each twisted pair surrounded by an associated ground shield. These twisted pairs typically receive complementary signal voltages, ie, one wire in the pair sees a +1.0 volt signal and the other wire in the pair sees a -1.0 volt signal. As such, these wires may be referred to as "differential" pairs, a term that refers to the pairs that carry differentia...
