The 3W Rule for Crosstalk in High Speed PCB Does It Still Work at 56G
For decades, the 3W rule for crosstalk in high speed PCB design has been a golden guideline: to minimize crosstalk, the center-to-center spacing between two traces should be at least three times the width of a single trace. But at 56G PAM4 signaling, does this classic rule still provide sufficient isolation? This pillar content analyzes…
