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...]
Rohde & Schwarz VNA Verifies Excellent PCIe 6.0 Performance Of High-Speed Cable
A live product demonstration from DesignCon 2023 highlights the outstanding PCIe 6.0 performance of both a Samtec Flyover® high-speed cable assembly and a Rohde & Schwarz® ZNA vector network analyzer. In this short video, Greg Vaught, VNA Product Planning Manager with Rohde & Schwarz, and Matt Burns, Technical Marketing Manager at Samtec, walk us through the setup and describe the products and results measured. A Rohde & Schwarz ZNA 67 Vector Network Analyzer is connected to a … [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...]
Improve Power Integrity and Signal Integrity With New Interconnects
A new connector system improves signal integrity by improving power integrity. Optimizing power integrity provides greater signal integrity margin and improves power and thermal efficiency. The design of a high-speed connector system's breakout region, or BOR, impacts signal integrity. The BOR of a power connector also impacts signal integrity. How do we create a BOR that minimizes parasitic inductance? PI + SI: A New Connector In this video from DesignCon 2023, Alex Wroten, … [Read more...]
Apollo Communication Hardware: A Fantastic Demonstration Of The Original Equipment
A working demonstration of the Apollo communication system -- the original Apollo S-Band communication hardware that was used in the Apollo moon missions in the 1960s and early 1970s -- was on display at DesignCon 2023. Marc Verdiell, CTO of the Samtec Optical Group, walks us through the setup. Marc is part of a team that is restoring this Apollo communication equipment to its original functional state. All equipment is on loan from private collections. The system operated at 2.1 GHz and … [Read more...]
New Cable Backplane System Achieves 56 Gbps PAM4 While Subject to Dynamic Cable Flexing
What Do Dynamic Cable Flexing and Space Invaders Have In Common? Our most popular live product demonstration at DesignCon 2023 was based on Space Invaders. When you see it you'll understand what I'm talking about. This demo is similar to others we’ve shown in the past. It demonstrates our high-speed connector systems in an environment mimicking our customers’ applications. But this time, visitors in our booth are actively bending Samtec’s twinax cable while we are taking measurements. And … [Read more...]
New Alignment Features Ensure Precision Alignment in Test & Measurement Applications
Samtec has developed an innovative, yet easy-to-use alignment technique for ensuring peak connector performance of precision, high-frequency compression mount connectors in test and measurement applications. The following explains the trend we were seeing and outlines the solution we developed to the common alignment challenge that was occurring. The Problem As data rates continue to push upward (224 Gbps PAM4) the need for precision, higher frequency compression mount test … [Read more...]
Samtec’s First 224 Gbps PAM4 Live Product Demonstration
There’s no end to the demand for bandwidth. Everything from 5G networks, streaming video, social media, augmented and virtual reality, and artificial intelligence and machine learning, are all pushing current-bandwidth limits. The next level is 224 Gbps PAM4. Visitors at DesignCon 23 saw promises and glimpses of 224 Gbps equipment and components. We are excited that we debuted our first 224 Gbps PAM4 live product demonstration. In this video, Ralph Page, Systems Architect at … [Read more...]
Why Did PCIe 6.0 Adopt PAM4? There Are Many Reasons.
Samtec is a proud member of the PCI-SIG® community, and we have been for many years. In conjunction with our friends at PCI-SIG, Jignesh Shah, Senior System Architect at Samtec, discusses PAM4 encoding, which is a new feature of the PCIe® 6.0 specification. New: The PCIe® 6.0 Specification In early 2022, PCI-SIG® released the full version of the PCI Express® (PCIe®) 6.0 specification. As with previous versions, the latest version doubles the data rate of the PCIe 5.0 specification and … [Read more...]
