The definitive high-speed design resource for every PCB designer
In this book, renowned engineer,author, and seminar leader Douglas Brooks teaches PCB designers how tosuccessfully design boards for any high-speed application. Brooks begins withan easy-to-understand electronics primer for every PCB designer, then offerspractical, real-world solutions for every important signal-integrity problem.Based on his legendary seminars, this book offers even more design rules,specific recommendations, examples, illustrations, and diagrams.
Coverage includes?
Essential electronics concepts: propagation, current, resistance, reactance, impedance, phase shifts, and more
EMI principles and controls: loop area, uncontrolled differential currents, and common mode currents
Controlling signal reflections: transmission lines, proper terminations, and trace layer design
Power system stability (bypass capacitor decoupling): Traditional approaches, and techniques based on power-system impedance
Eliminating forward crosstalk, and eliminating or controlling backwards crosstalk
Power-system conditioning: power-system plane design and correct board stackups
Lossy lines and eye diagrams: skin effects, dielectric absorption, and more
Reviews:
This book details design solutions to classic signal integrity problems and educates the novice in understanding the reasoning behind the solutions. There is a lot of nonsense being written about signal integrity and few people have the resources to filter out the chaff from hay. This book proves every principle presented with tested board layouts, demonstrated engineering principles, or documented laboratory results. Some people can see the world in formulas and some see the world pictorially. This book is rich in both forms of expressionism and its presentation will not exasperate the PCB designer who sees the world visually, or frustrate the engineer seeking equations for design representation. This book has been added to the required reading list for our PCB layout designers and product development engineering teams.
Brook's book is exceptional in the clarity of the writing, esp. in explaining key concepts that most engineers are fuzzy on. This book is great at giving engineers an intuitive feel for basic electromagnetics and how it relates to signal integrity and emi.
It's main strength (and to some it's major weakness) is that it avoids the mess of equations of better known books like Johnson's "High-Speed Digital Design". Brooks is also a good writer, and he writes very clearly. Don't get this book, if you already understand the subject, since it doesn't cover advanced material. However, this is essential reading for those who don't have a clue or for those (like me), who've memorized a lot of emi guidelines, without really understanding why they're necessary.
Given the book's title, the only area of improvement I can think of is a chapter or appendix on basic pcb manufacturing and terminology (buried vias, microvias, antipads, etc).
