Designers pushing the limits in their application can run into situations where the XO performance is inadequate for their next design due to the way it reacts to the noise and ripple in the power supply. To achieve optimal performance, they most likely will find they will need to do more than a simple datasheet evaluation to select their next XO. Read on for details on a PSNR test method to help select an optimal XO.

When is it appropriate to have a continuous plane, split planes, or no planes under an RJ45 connector? This article from Zachariah Peterson takes a closer look.

Future data center and high-speed computation require faster connectivity to meet the increasing set of applications and bandwidth. IEEE and OIF have developed 106-112 Gbps per lane electrical interface specifications P802.3ck1 and CEI-112 G2 for the 400 GbE system. To meet the next-generation system bandwidth requirement, industry and standard bodies recently kicked off new projects aiming at 800 GbE or even higher speeds beyond 1 TbE. So what comes next beyond 112 Gbps for electrical interfaces over copper (Cu) channels? Will it be 224 Gbps?

SIJ technical editor, Eric Bogatin, shares his picks for great watches or reads for this month.

EDI CON Online, an interactive event being held online Tuesdays in October 2020, has opened registration. Attendees can register for free in a single sign-on portal for all technical sessions, workshops, and keynotes occurring every Tuesday in October (and on demand after the event). 

The first available roughness models, such as Hammerstad, Hemispherical, Huray aimed to predict loss increase due to metal roughness. However, there was a problem. Read on to find out more.

Check out this article from Mike Hertz that details specifically how The Track measurement operator on oscilloscopes can be used to identify timing issues.

EDI CON Online, an interactive event being held online Tuesdays in October 2020, has announced its platinum sponsors and keynote speakers. In its second year, the event’s technical, workshop, and keynote sessions will occur at no cost to attendees and will be available live with question and answer sessions or on demand after the event.

Signal integrity engineers almost always have to work with S-parameters. If you have not had to work with them yet, then chances are you will sometime in your career. As speed moves up in the double-digit GB/s regime, many industry standards are moving to serial link-based architectures and are using frequency domain compliance limits based on S-parameter measurements.
