摘要： A differential transmission line with a common mode notch filter includes adjacently arranged, repeating differential transmission line pair sections. The sections have lengths that are each equal to half of an electric wavelength of a lowest frequency of a common mode electromagnetic wave to be suppressed during transmission of an electric signal over the differential transmission line. Each section includes a pair of conductors separated from one another by a spacing. The width of each conductor and the spacing between the conductors of each section vary over the length thereof according to a same pattern such that at every point over the length of each section a differential mode impedance of the differential transmission line is identical. A common mode impedance of the differential transmission line changes periodically in accordance with the lengths of the sections.

摘要： A host networking device networking interface is automatically configured. The interface is initially configured to operate in a single-link mode in which multiple network communication lanes of the interface cooperatively provide a single communication link. If a signal is not present on any communication lane, then the interface is configured to operate in a multiple-link mode in which each lane provides a separate and different communication link, and is operated in the multiple-link mode. If a signal is present on every communication lane, and if the single communication link has been established with another networking device over all the lanes, then the interface is operated in the single-link mode. If a signal is present on every communication lane, but if the single communication link has not been established over all the lanes, then the interface is configured to operate in the multiple-link mode and is operated in the multiple-link mode.
