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...]
New prodesign Acceleration Card Includes Samtec NovaRay® Extreme Density Arrays
The recent popularity and interest in ChatGPT underscore the progress AI has made in affecting everyday life. Who has asked ChatGPT to finish a homework assignment or write a blog? (For full disclosure, this blog has been written by a real person. Or has it? 😉) In any case, the backbone of chatbots like ChatGPT and similar services are high-performance compute platforms enabling neural networks and AI acceleration in data centers. Obviously, GPUs have a leadership position in AI hardware … [Read more...]
Should I Use a PCB or Cable Backplane?
Selecting a backplane design requires tradeoffs specific to a particular network topology and application. In some cases, the assessment of PCB vs cable backplane is not an “either/or” but a combination approach. This blog post, based on a conversation with Samtec’s Andrew Josephson, Brandon Gore, and Jonathan Sprigler, aims to answer some of the most common questions that come up when deciding should I use a PCB or cable backplane for a high-speed design? How do the two approaches compare on … [Read more...]
PCIe 6.0 Data Routed From New Chip-Adjacent Connector To Front Panel
PCIe 6.0, optics, 112 Gbps PAM4, linear direct drives, PCIe over fiber. Samtec displayed a variety of live product demonstrations - both optical and copper - at OFC 2023. Two demos, both in tandem with our partner Cadence, received much attention. Both demonstrated cutting-edge data rates, one at 112 Gbps PAM4, and the other is 64 GT/s, PCIe 6.0 data rates. And both show excellent signal integrity performance from our Samtec Flyover® High-Speed cable systems. This blog and video … [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...]
High-Speed Cable System and Blockchain ISI Demonstrate Excellent 112 Gbps PAM4 Performance
OFC 2023 saw the world premiere of Credo’s DOVE 800 family, teamed with a Samtec Flyover cable assembly, and a Samtec blockchain ISI board, both demonstrating outstanding performance at 112 Gbps PAM4. The DOVE 800 is a retimer, with eight lanes of 100 G to 100 G. Ralph Page, Systems Architect at Samtec, walks us through the two signal paths. In channel one, a BERT is generating eight lanes of 112 Gbps PAM4, PRBS 31-bit data, which travels through low-loss coax cable to a Samtec … [Read more...]
New Samtec Flyover® Cable System Extends Signal Reach At Next Gen Data Rates
The insatiable bandwidth demand for next gen data rates is driven by applications like the cloud, artificial intelligence, machine learning, supercomputing, and 5G. In this video from OFC 2023, Matt Burns walks us through a live product demonstration of a Samtec Flyover® Cable System showing excellent performance at 112 Gbps PAM4. The signal source is a Cadence 112 G ELR SerDes PHY, and the signal is run through a Samtec Flyover cable assembly that’s up to the task. The Cadence … [Read more...]
Integral Ground Plane For Data Rate, Power, and Processing
Cutting-edge data rates have received much well-deserved press in the electronics media. New 56 and 112 Gbps PAM4 systems are in operation with verified, sustainable performance, and we’re on the doorstep of 224 Gbps PAM4. Having said that, the majority of Samtec customers don’t need these extreme data rates. For many designers and many applications, high speed, if it’s needed at all, is 10 Gbps or less. They need a reliable connector system capable of handling those slightly higher data … [Read more...]
Cutting Edge High-Speed Cable Performance Measured By The World’s First 53 GHz Scalable VNA
In this live demonstration from DesignCon 2023, the performance of a Samtec high-speed cable system is measured by the world’s first scalable VNA. Matt Burns (Technical Marketing Manager, Samtec), and Mike Resso (Signal Integrity Application Scientist, Keysight) explain the demo and equipment. The scalable VNA is Keysight's Digital Interconnect Test System, with 16 ports that are expandable to 32 ports at 53 GHz. In this demonstration, Mike has calibrated all 16 ports of the Keysight PXI-VNA … [Read more...]
