High Speed Digital Design A Handbook Of Black Magic Pdf

[Glauco Schlembach]

Consideredthe original "bible" of high-speed design issues, High-Speed Digital Design focuses on a combination of digital and analog circuit theory. This comprehensive volume helps engineers who work with digital systems shorten their product development cycles and fix their latest high-speed design problems.

NOTE: This book is not required for the High-Speed Digital Design Seminar, but it makes a terrific companion. The seminar treats a subset of the book material, and in a different way more condusive to live explanations. The book, being 447 pages in length, obviously delves into the subject matter in greater detail. Think of the seminar as an introduction and, if you like it, get the book for on-the-job reference.

Chapters 4 begins with an introduction to the properties of a simple, uniform, infinite transmission line and works up to an understanding of transmission line losses, reflections, and various common cases of source and load impedances. It considers reflections from reactive loads and ends with a discussion of how a large number of loads connected to a common bus loads the bus, changing both its impedance and propagation delay.

Chapter 5 introduces the concept of returning signal current, a notion crucial to the understanding of crosstalk in high-speed digital layout. With the importance of a solid reference plane understood, the chapter presents a number of layer stack examples.

Chapter 7 gives a brief look at the mechanical properties of vias and the parasitic capacitance and inductance of vias, a subject treated much more thoroughly in the book, High-Speed Signal Propagation. Chapter 8 explores the architecture of a power system. It looks into issues of voltage fluctuation and DC droop. The chapter presents an electrical model of a capacitor, and discusses the relation of capacitor packaging to the equivalent series inductance of a capacitor, a subject more thoroughly presented in the High-Speed Digital Design Seminar. The chapter concludes with notes concerning the properties of three popular capacitor dielectric materials.

Chapter 9 extends the idea of returning signal current to explain the mutual-inductive mode of crosstalk within connectors. It shows an example of how connectors create EMI. It then considers the parasitic capacitance of a connector its impact on the loading of a multi-drop bus. The Chapter includes notes on special measurement procedures for connector, leading to a discussion of the importance of continuity of the reference planes at the board-to-connector interface. The chapter ends with discussions of differential connectors

Appendix A collects highlights from each section, listing the most important ideas and concepts presented. It can be used as a checklist for system design or as an index to the text when facing a difficult problem.

The reader need not have a background in electrical engineering or circuit theory to read and understand this book. No mathematics are used beyond simple algebra and 1st-order derivatives. The authors do assume a general familiarity with digital logic and the concepts of voltage and current.

This is a book for digital designers. It highlights and explains analog circuit principles relevant to high-speed digital design. Teaching by example, the authors cover ringing, crosstalk, and radiated noise problems which commonly beset high-speed digital machines.

At high speeds, where fast signal rise times exaggerate the influence of analog effects, engineers experience a completely different view of logic signals. To them, logic signals often appear hairy, jagged, and distorted. For their products to function, high-speed designers must know and use analog principles. This book explains what those principles are and how to apply them.

Readers without the benefit of formal training in analog circuit theory can use and apply the formulas and examples in this book. Readers who have completed a first year class in introductory linear circuit theory may comprehend this material at a deeper level.

"Dr. Howard W. Johnson and Dr. Martin Graham have blessed us with a text that in many ways addresses exactly this juxtaposition of designer and engineer in the high-speed board world....this is one of the finest efforts to come along in the field of applied high-speed digital design because of its focus on providing tools for the whole design team bringing a high-speed product to life. For all the PCB designers and circuit designers out there, buy it; read it; keep it."- Dan Baumgartner, Printed Circuit Design

"'High-Speed Digital Design'...treats the gray area between signals that are digital, and the analog aspects that are so important when you want your digital buses to behave at higher and higher speeds - not a trivial task. This book is there to help, with serious advice and good philosophy."- Bob Pease, Electronic Design

"Engineers who must make high-speed circuits work will find this book invaluable. Johnson and Graham strike what seems to me to be just the right balance between rigor and nuts-and-bolts practicality. The book should be must reading for EE students who aspire to work in digital-hardware design. It should also occupy a place in the libraries of most of the experienced practitioners of the art." - Dan Strassberg, EDN

The mathematical spreadsheet concept is not unique. Math spreadsheet applications are available from several vendors. Popular versions include MathCad, Mathematica, and MatLab. Any of the three tools can accomplish the basic purpose of recording graphics, text and equations.

We happen to be MathCad users, and for a very good reason: the MathCad syntax looks much like ordinary equations. That makes it a great teaching tool. Other tools may be more popular, or more powerful, but we find MathCad to be very good for presentation work, so our collection of high-speed design utilities have been formatted for use with the MathCad application. You will need the MathCad application to run the spreadsheets. If you use a different spreadsheet, it's not difficult to convert the equations to your format.

The "MathCad modelling scripts" download is a .zip file. It includes everything from Appendix C encoded for MathCad, but with additional examples. The scripts are provided in both MathCad v.13 syntax and also human-readable .pdf format in case you need to port the equations to another brand of mathematical spreadsheet. Also included in the .zip file is a simple short-line transmission line simulator that incorporates the effects of source impedance, load impedance, transmission line delay, characteristic impedance, and risetime of the driving waveform. The simulator does not incorporate skin-effect or dielectric loss.

Focused on the field of knowledge lying between digital and analog circuit theory, this new text will help engineers working with digital systems shorten their product development cycles and help fix their latest design problems. The scope of the material covered includes signal reflection, crosstalk, and noise problems which occur in high speed digital machines (above 10 megahertz). This volume will be of practical use to digital logic designers, staff and senior communications scientists, and all those interested in digital design.

Howard W. Johnson is president of Olympic Technology Group, Inc., of Redmond, Washington, a digital electronic design and consulting organization. Before founding the firm, he was Manager of Technology and Advanced Development at Ultra Network Technologies, a manufacturer of gigabit-per-second local area networks for supercomputers. Since obtaining his Ph.D. in 1982 from Rice University, he has specialized in the design of high-speed digital communications and digital signal processing systems.

Martin Graham has been a Professor of Electrical Engineering and Computer Sciences at the University of California at Berkeley since 1966, where he teaches the design of reliable and manufacturable electronic systems.

Focusing on a combination of digital and analog circuit theory, this comprehensive volume will help engineers who work with digital systems, shorten their product development cycles, and fix their latest high-speed design problems.

This is a practical two-day seminar course, filmed in front of a live audience by a professional documentary film crew, taught by a man with extraordinary capabilities. His seminars have been seen by over 10,000 engineers worldwide, and was for 20 years among the most popular summer engineering short courses ever offered at the University of Oxford.
