Nvidia had its annual GTC gathering of AI developers, fans, media, and gamers recently. The newly announced Nvidia Blackwell platform is scheduled for release in late 2024/early 2025. Blackwell will likely lead to another round of "world domination" - I say that tongue in cheek - for the Nvidia. One thing that struck me is the raw performance the Nvidia GPUs support. Imagine the engineering that goes into develeoping signal channels for the HBM, NVLink, PCIe, CXL, and numerous other … [Read more...]

An Optical Illusion? Maximum Signal Density and Design Flexibility
Samtec FireFly™ mid-board optical cable systems boast the industry’s leading miniature footprint, enabling maximum signal density, and of course signal integrity over longer distances. That's a good thing because designers are facing longer-reach applications, increasing bandwidths, and tighter spaces. FireFly™ mid-board optical cable assemblies provide high-performance versatility for data rates up to 28 Gbps per channel. The miniature footprint allows for higher density and closer proximity … [Read more...]
New Linear Direct Drive At 112 Gbps PAM4
Straight from DesignCon 2023, Kevin Burt, Samtec's Director of Happiness, walks us through a proof-of-concept for an on-package, or near-package, linear direct drive electrical channel that gives us a 100-meter link at 112 Gbps. These links could be used in mid-board optical and copper designs using Samtec Flyover® cable assemblies or high-speed mezzanine connector sets, as well as for full-channel front-panel and back-panel cable applications. A Multilane Pattern Generator generates a 112 … [Read more...]
Samtec Releases New Evaluation and Development Kits
Readers of the Samtec blog know that the demand for data keeps increasing. Rightly, data center applications may be the first to enter one's mind. However, faster speeds are required in AI/ML, Mil/Aero, Automotive, Medical, Instrumentation, and many other applications as well. Engineers developing new products at higher speeds need reassurance that the components they select work as advertised. Samtec-designed Evaluation and Development Kits simplify the interconnect design process and reduce … [Read more...]
Samtec SI Technologists to Present at EDI CON Online 2022
"I'm lovin' it." "Can you hear me now?" "Just do it." "Where High Frequency Meets High Speed" The first three taglines are a part of pop culture lexicon. The last describes an annual technology event - EDICON Online 2022 - focused on training and informing engineers on that latest high-performance technologies, solutions, trends and design techniques. The world of high-frequency and high-speed is converging as never before. Real-world and modeled 224 Gbps PAMx system design … [Read more...]
Linear Direct Drive Proof-of-Concept Can Support 100 G+ Signaling
This video from DesignCon 2022 shows a proof-of-concept for an on-package, or near-package, direct-drive electrical channel that can support 100 G + signaling. These drives could be used in mid-board optical and copper designs using Samtec Flyover® cable assemblies or mezzanine connector sets, or for full-channel front-panel and back-panel cable applications. Samtec’s Kevin Burt walks us through the demo, the results, and a brief discussion of the benefits. What's Going On On … [Read more...]
