Hi, The crosstalk theory says that the values of far end crosstalk will be negative and near end cross talk will be positive. If that is the case, does the negative far end crosstalk on the victim line leads to any undershoot problems? or it just reduces the noise margin levels in the victim lines? When to worry about overshoot and undershoot problems due to crosstalk?
