High-Speed Digital System Design: A Handbook of Interconnect Theory and Design Practices
A cutting-edge guide to the theory and practice of high-speed digital system design
An understanding of high-speed interconnect phenomena is essential for digital designers who must deal with the challenges posed by the ever-increasing operating speeds of today's microprocessors. This book provides a much-needed, practical guide to the state of the art of modern digital system design, combining easily accessible explanations with immensely useful problem-solving strategies. Written by three leading Intel engineers, High-Speed Digital System Design clarifies difficult and often neglected topics involving the effects of high frequencies on digital buses and presents a variety of proven techniques and application examples. Extensive appendices, formulas, modeling techniques as well as hundreds of figures are also provided.
Coverage includes:
* A thorough introduction to the digital aspects of basic transmission line theory
* Crosstalk and nonideal transmission line effects on signal quality and timings
* The impact of packages, vias, and connectors on signal integrity
* The effects of nonideal return current paths, high frequency power delivery, and simultaneous switching noise
* Explanations of how driving circuit characteristics affect the quality of the digital signal
* Digital timing analysis at the system level that incorporates high-speed signaling effects into timing budgets
* Methodologies for designing high-speed buses and handling the very large number of variables that affect interconnect performance
* Radiated emission problems and how to minimize system noise
* The practical aspects of making measurements in high-speed digital systems
Why Read This Book
You will gain a rigorous, application-focused grounding in how high-speed signals behave on real interconnects so you can diagnose and prevent signal- and power-integrity failures before they reach production. The book pairs clear theoretical foundations (transmission lines, S-parameters, time- and frequency-domain behavior) with practical design recipes, measurement techniques, and worked examples you can apply to PCBs, backplanes, cables, and packages.
Who Will Benefit
Engineers and technical leads working on high-speed digital boards, links, or systems who need to design, model, or troubleshoot interconnects and signal/power integrity in production hardware.
Level: Advanced — Prerequisites: Undergraduate-level circuit analysis and electromagnetics, familiarity with digital logic and PCB concepts, and a working knowledge of complex impedance and basic frequency-domain concepts.
Key Takeaways
- Analyze high-speed interconnects using transmission-line theory and S-parameter concepts to predict time- and frequency-domain behavior.
- Predict and mitigate signal-integrity problems such as reflections, ringing, crosstalk, and dispersion through modeling and termination strategies.
- Design PCB stackups, routing geometries, connector and cable interfaces, and return paths to optimize signal and power integrity.
- Apply measurement and characterization methods (TDR/TDT, VNAs, time-domain oscilloscope techniques) and interpret results to validate models.
- Model channels with SPICE and network-parameter approaches and use those models to guide layout and component selection.
- Evaluate power-distribution and grounding practices to control ground bounce, PDN impedance, and EMI interactions in high-speed systems.

Languages, Platforms & Tools
How It Compares
Covers similar theoretical and measurement depth as Howard Johnson and Martin Graham's High-Speed Digital Design but with a stronger emphasis on interconnect theory, S-parameters, and worked application examples; Eric Bogatin's books are more tutorial and modernized, while Hall's handbook is denser and more reference-oriented.
