Emerging 100 Gigabit Ethernet and 400 Gigabit Ethernet requirements for communication networks have put increasing demands on Internet infrastructure. New methods of design, validation, and troubleshooting to optimize high speed digital channels are being employed in the R&D laboratory. This article discusses new concepts for serial link design and analysis as applied to physical layer test and measurement techniques. Novel test fixtures and signal integrity software tools will be discussed in real world applications in the form of design case studies.
In this paper, we introduce a special class of resonant structure - the Beatty Standard - along with other classic resonators. We examine closely the resonant Beatty Standard, its impedance profile, loss characteristics, and its application to printed circuit board material property extraction. Suited for 32 Gbpsec simulation requirements, the Beatty Standard not only provides engineers a compact structure to perform material property extraction, but also help with establishing a robust design flow.
