Demonstration of Differential Pair Signaling

PCB architecture often requires compromises in the routing of a differential pair. What do these compromises do to the signals the PCB traces are meant to guide? This demonstration will demonstrate the effects of asymetry, skew, interconnects, stubs and loose coupling.


Bill Spence of Gentex Corporation

Bill Spence started his electronics training by enlisting in the Army Security Agency. After receiving a Top Secret Security Clearance, Specialist Bill Spence worked under the NSA on a signal intelligence site (COMINT) in Germany. Upon returning to the States, Bill continued his studies and received his first Associate's Degree in Electrical Engineering from Valparaiso Technical Institute. Bill's first job after graduating in 1976 was the Engineering Department's Senior Instrumentation Technician position at Electro-Voice in Buchanan, Michigan. Bill went on to earn another Associate's Degree in General Studies from Southwestern Michigan College and take Chemistry and Calculus courses from Indiana University. Bill finished his requirements for a Bachelor's Degree in Electrical Engineering Technology from Andrews University. All the while, Bill rose from technician to Senior Microphone Design Engineer during his twenty-four years at Electro-Voice. Entering Gentex on April 2000, Bill was first assigned the Senior Microphone Engineer position, then the Photonics Department Senior Research Engineer, and finally for the last ten-years the Senior EME Engineer. When Bill is not writing presentations and working with the mirror development teams, he spends his time with his wife studying American Colonial History and practicing marksmanship with flintlock musket.
