PCB Design of Gb-s Differential Lines, July 2006
Differential transmission lines are becoming very common on printed circuit boards (PCBs), for carrying serial data at Gigabit/second (Gb/s) rates. It is usually assumed that the electromagnetic compatibility (EMC) of such transmission lines will be better than the single-ended lines they replace – but in fact their EMC can easily be degraded by typical PCB design and routing techniques – to the point where it can be little better than that of single-ended lines. This paper presents an overview of the PCB design problems and their solutions for maximising the EMC of differential transmission lines operating at all data rates up to Gb/s. No new work is presented, but the references are very recent and this paper presents the techniques all in one place, in a style that can be understood and used by PCB designers.

EMC Standards is a world-leading resource for all things EMC and EMI related. Our website is packed full of both free and paid-for content, including:
- Online quiz
- Webinars
- Training quiz
- And much more!
Electromagnetic Engineering (EMgineering) is the basis for proven good design practices for signal integrity (SI), power integrity (PI), and the control of EMI emissions and immunity (EMC).
Our aim is to help people learn how to more quickly and cost-effectively design and manufacture electronic equipment (products, systems, installations, etc.) to meet functional (i.e. SI/PI) specifications and conform to EMC standards, directives and other requirements.
Such equipment should benefit from reduced warranty costs and financial risks, whilst improving uptime, competitiveness and profitability.
We also cover basic good electrical safety engineering; and the Risk Management of Electromagnetic Disturbances / EMI, whether for Functional Safety or other types of risk.
