Search Results for: Transmission Lines In Digital Systems For Emc Practitioners

This is a brief but comprehensive book covering the set of EMCskills that EMC practitioners today require in order to besuccessful in high-speed, digital electronics. The basicskills in the book are new and weren’t studied in mostcurricula some ten years ago. The rapidly changing digitaltechnology has created this demand for a discussion of new analysisskills particularly for the analysis of transmission lineswhere the conductors that interconnect the electronic modules havebecome “electrically large,” longer than a tenth of awavelength, which are increasingly becoming important. Crosstalk between the lines is also rapidly becoming asignificant problem in getting modern electronic systems to worksatisfactorily. Hence this text concentrates on the modelingof “electrically large” connection conductors wherepreviously-used Kirchhoff’s voltage and current laws andlumped-circuit modeling have become obsolete because of theincreasing speeds of modern digital systems. This has causedan increased emphasis on Signal Integrity. Until as recently as some ten years ago, digital system clockspeeds and data rates were in the hundreds of megahertz (MHz)range. Prior to that time, the “lands” on printedcircuit boards (PCBs) that interconnect the electronic modules hadlittle or no impact on the proper functioning of those electroniccircuits. Today, the clock and data speeds have moved intothe low gigahertz (GHz) range.
