Abstract
A printed circuit board (PCB) for coupling to an automotive Ethernet connection includes first and second board conduction traces, a first off-board conductor coupled to the first trace at a first contact point spaced from an edge of the PCB, and extending over the PCB from the first contact point to the edge for connection a first off-board conduction path, a second off-board conductor coupled, adjacent to the first off-board conduction path, to the second trace at a second contact point spaced from the edge of the PCB, and extending over the PCB from the second contact point to the edge for connection the second off-board conduction path. The off-board paths are a power path and a signal path. A loop in one of board conduction traces inductively couples that one the board conduction traces to a respective one of off-board conduction paths.
