Hello,
I saw a video on Differential Pairs by Rick Hartley.
He mentions that differential pair length matching is not as critical as it has been considered by many pcb designers. He says it takes 50mm difference of length for a 10Gbps differential pair to fail. This fact doesnt make sense to me.
He also says that he has almost always never length matched a differential pair and it has always worked for him. Then what is the reason we spend so much time and energy trying to length match critical differential pairs to within say 5mil or 10mil.
Pls say what you think about this.
Regards
RAJAT
