DEVICE AND METHOD FOR TRANSMITTING DIFFERENTIAL DATA SIGNALS

摘要

A device, in particular a pre-assembled transmission cable, is used to transmit differential data signals in a high-speed data connection. The device contains a circuit board with a conductor pair with two signal conductors for transmitting the differential data signal. An output line which is insulated from the conductor pair is paired with the conductor pair, the output line running parallel to the signal conductors in a non-interrupted manner and additionally being connected to a measuring conductor via at least one damping element. By virtue of the configuration, an undesired common-mode signal component is at least partly coupled into the output line, where the signal component is absorbed during operation.

1. An apparatus for signal transmission for differential data signals, comprising:
a printed circuit board having a conductor pair with two signal conductors for transmitting a differential data signal, and a decoupling line associated with said conductor pair, said decoupling line being insulated from said conductor pair and running symmetrically and without interruption in relation to said signal conductors, said printed circuit board further having a ground connector and at least one attenuating element, said decoupling line being connected to said ground conductor via said at least one attenuating element such that a common mode signal component is at least in part output to said decoupling line, and attenuated, during operation.
