Abstract: Traces on a PCB can be spaced closer together than in conventional layouts, which previously required the pair-to-pair spacing for the high-speed differential stripline signals to be at least 5H if the signals are originating from the same source and 7H when the signals on two pairs of transmission lines in the traces originate from different sources. Traces may be spaced closer together when, for example, a ratio of the core height to the prepreg height of the printed circuit board is approximately equal to one. Traces may be spaced closer together when, for example, a ratio of the trace spacing distance to the core height distance is less than approximately one.
