Available now in production quantities, Samtec AcceleRate Slim Direct-Attach Cable Assemblies target high-density applications in computing, datacom, AI, and shielded Gigabit Ethernet designs.

VIAVI Xgig CXL Exerciser has received CXL 2.0 Gold Suite certification from the Compute Express Link Consortium. 

Samtec will be demonstrating next-generation, high-performance copper and optical interconnect solutions at the upcoming SC24.

Ideal circuit elements are a powerful tool that enables us to explore the real world in virtual prototypes. Engineers can often gain insights and reach an optimized design faster using a virtual prototype than would be possible when building a real physical prototype.

ZTE Corporation, in partnership with Turkcell, has completed the world's first end-to-end 800GE with SRv6 and EVPN ultra-high-speed field test between different sites. This milestone not only verifies the excellent performance of advanced technologies, but also injects strong impetus to global network growth.

Awarded the Best Paper Award at DesignCon 2024, this paper demonstrates that, for correlated data with PDN impedances in the sub-mΩ level, the impedance extracted from same-location top-bottom measurement can be significantly different from same-side adjacent via pair measurement, even if the physical separation is in the order of a mm

Wild River Technology's new advanced channel modeling solution helps achieve extreme signal integrity design to 70 GHz and supports a 3D EM solver analysis modeling versus time and frequency domain measurement methodology.

This paper, awarded the Best Paper Award at DesignCon 2024, explores what is meant by bandwidth during the standardization process, the implications of test and verification attached to certain bandwidth requirements, as well as differences between acquisition range, band limited filters, and s-parameters for time domain processing. 

Making accurate time interval error (TIE) or phase noise measurements of a periodic signal presents a number of challenges. The program jitterhist includes algorithms and settings to provide accurate TIE measurement results for periodic waveforms with significant amounts of high-frequency measurement/modulation noise as well as for waveforms having multiple unit intervals of low frequency modulation when the time span of the samples includes more than one period of the modulation.
