Added indicator to show when differential impedance is within tolerance of a target impedance. Corrected a conversion issue in the asymmetrical stripline calculator when switching between metric and imperial units. Edge coupled internal asymmetric differential pair Edge coupled embedded differential pair.For the signal trace of width W and thickness T, separated by distance H from a ground (or power) plane by a PCB dielectric with dielectric constant εr, the characteristic impedance is:)⎥⎦ ⎤ ⎢ ⎣ ⎡ ε Ω= 0.8W+ T 5.98H ln +1.41 87 Zo.Although similar in structure to the symmetric stripline model, this model accounts for the transmission line trace that is not balanced precisely between the two planes.

Where: Z0 Z 0 = characteristic impedance of the asymmetric stripline in ohms (Ω).
