Table 9 Summary of Time-domain SDD for pair 4 of IT3-32mm for 50% pin density configuration

3.2.4 Time-Domain Crosstalk (connector only)

The total differential cross-talk values in % for at 60ps (20% to 80%) rise time and 5.25GHz

bandwidth for center pair 8 of the fully populated model and, pair 4 for 60% and 50% pin density

are shown in Figure 60, Figure 61 and Figure 62.

The outer column (top row as portrait in Figure 60) exhibits higher crosstalk as it is only

surrounded by one ground plane.
