  • Multi-pair differential lines printed circuit board common mode filter
    Patent number: 9544991
    Abstract: Multi-pair differential lines printed circuit board common mode filters are generally described. In one embodiment, the apparatus includes a multi-layer printed circuit board, a first signal line and a second signal line forming a first differential pair on a first layer of the printed circuit board, a second differential pair on the first layer of the printed circuit board, and a common mode filter on a second layer of the printed circuit board, the common mode filter comprising an absence of a predominantly occurring dielectric material of the printed circuit board, the common mode filter spanning an area directly below at least a portion of both the first and the second differential pairs. Other embodiments are also described and claimed.
