He frequently conductstechnical workshops for digital engineers at OxfordUniversity and other sites worldwide: www.sigcon.com.
DR. MARTIN GRAHAM is Professor Emeritus ofElectrical Engineering and Computer Sciences at theUniversity of California at Berkeley. He specializes inteaching the design of reliable and manufacturableelectronic systems.
Raves for Dr. Johnson's previous classic,High-Speed Digital Design!
"....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
Faster and farther: State-of-the-art signal transmission techniques
InHigh-Speed Signal Propagation, Howard Johnson and Martin Graham bring together state-of-the-art techniques for building digital interconnections that can transmit faster, farther, and more efficiently than ever before. Packed with new examples and never-before-published high-speed design guidance, this book offers a complete and unified theory of signal propagation for all metallic media, from cables to pcb traces to chips. Coverage includes:
- Managing tradeoffs between speed and distance
- Physical theory of signal impairments: skin and proximity effects, dielectric loss, surface roughness, and non-TEM mode propagation
- Generalized frequency- and step-response models
- Calculation of time-domain waveforms from frequency-domain transfer functions
- Differential signaling: Edge-coupled and broadside-coupled differential pairs, bends, intra-pair skew, differential trace geometry impedance, crosstalk, and radiation
- Inter-cabinet connections: Coax, twisted-pair, fiber, equalizers, and LAN building wiring
- Clock distribution: Special requirements, repeaters, multi-drop clock distribution, jitter, and power filtering
- Simulation: Frequency domain simulation methods, Spice, and IBIS

NOTE FROM THE AUTHOR
Welcome, and thank you for your interest in High-Speed Signal Propagation: AdvancedBlack Magic. This is an advanced-level reference text for experienced digital designers whowant to press their designs to the upper limits of speed and distance.If you need to transmit faster and further than ever before, this book is here to help.You'll find it packed with practical advice.
The material in this book has been honed during my many years of work as chieftechnical editor of standards for both Fast Ethernet and Gigabit Ethernet—projects which, Ihope, have touched your life in a favorable way. During those and many other projects, themodels and concepts described here have been of invaluable service to me. Now I'd like topass them on to you.
When you are done reading, share your knowledge with those around you as mytechnical mentor, Martin Graham, has done with me. Educate your coworkers. Educate yourmanagement. Above all, continue to educate yourself. If this book inspires you to advanceyour understanding with even one laboratory measurement, then I will know you are on theright track.
I would also like to say it has been a great pleasure teaching and working with manyof you through my classes and lectures. Above all, I appreciate those who take the time toshare with me their thoughts, their concerns, their dreams, and their problems. It alwaysinterests me to hear about real experiences from real engineers.I wish you the best of luck on your next design.
See you on the Internet,
Dr. Howard Jo
