Signal Integrity Design Fundamentals

WHAT EXACTLY ARE differential impedance traces, and how do they work?I remember a story from a former colleague about how their engineering team had spent nearly a month trying to solve a mysterious bit error rate (BER) issue on a seemingly well-designed and otherwise sound PCB. After many painstaking diagnostic hours, not to mention added resources and a looming release date, they finally found their answer. What was it? I'll get back to that.
