transitions. All PCB traces coming out from the vias have been matched to 10.507mm. The results

at various frequencies of interest are summarized in Table 22.

Figure 79 and Figure 80 show the power sum of NEXT and FEXT for the cascaded model (vias

+ connector + vias) of the single-ended center port.
