Suppose I have two clock lines that run parallel to each other for a significant distance (6" or 12"). They are completely synchronous (equal signal). Assume also that they are series (source) terminated. These two lines are (perfectly) common mode coupled (as opposed to differential). I have two questions: 1. What are the cross-talk implications, if any? 2. Are the cross talk implications different if they are/are not matched length?
