Figures 3 and 4 respectively show for
pin pairs on rows A-B and D-E, the
reflection and rise time degradation of
the odd mode as a function of rise
time. At larger rise times the reflection
curves converge to 0%, because the
transmission line behavior of the pins
disappears at lower frequencies. At the
lower rise times, the reflection
coefficient still stays below 20%.
Figures 5 and 6 show the multi-line
forward, respectively backward cross
talk on the same pin pairs A-B and D-E
i.e. the differential signal at the far- and
the near-end of these pairs, when the
neighboring pin pairs are excited in
phase with differential signals. These
worst case results show that for a rise
time of 350 ps, the forward crosstalk is
less than 2% and the backward
crosstalk is about 10%.
