3.1.1.2 60% density pin assignment
Page 10
Figure 13 shows the corresponding SDD for pair 4 for 60% pin density configuration. The SDD
results are summarized in Table 3. Figure 14 - Figure 15 and Figure 16 - Figure 17 show the power
sum and ICR profile comparison with the IEEE 802.3ap spec for NEXT and FEXT, respectively.
