Chapter 31 Summary: Differential Signaling Chapter 30 detailed the uses and limitations of single-ended signaling. Chapter 31 explains why engineers often move up to differential signaling – it has much greater immunity to noise than single-ended signaling, and creates less noise as it switches. But unlike the single-ended type, with differential signaling each data path requires two wires, two connector pins, two drivers and two receivers. The reader will learn which conditions call for differential signaling and which design rules can be counterproductive when using such signaling. Previous Chapter | Next Chapter
