Abstract
Systems and assemblies are provided for transposition channel routing where the characteristics of an escape route can be modified on a printed circuit board (PCB) in a manner that reduces crosstalk and realizes significant signal quality improvement. The techniques involve 'transposition' of a signal line pair on the PCB, reduces effect coupling coefficients for individual aggressor signals, thereby reducing the crosstalk. Transposition channel routing techniques can also be applied to other areas on a PCB (e.g., other than escape routes) where space is constrained and other mitigation techniques are not possible. The PCB can include an array of contact pads, a plurality of signal line pairs that include an escape route. One or more transposition junctions disposed within the escape route can route a signal line pair from a first routing channel in the escape route into a second routing channel in the escape route.
