With the recent introduction of PCIe® Gen 4 servers and engineering work stations, designers require faster optical links for networking and accelerator interfaces. Samtec’s new PCIe Gen 4 adapter card doubles the speed over the Gen 3 card and easily plugs into any PCIe slot. Giri Tumu, Samtec’s Optics Application Engineer, walks us through a live demonstration of our latest Gen 4 optical PCIe product. The demo includes a PCIe Gen 4 server and a Non-Disruptive Migration (NDM) storage end … [Read more...]
FireFly Technology Enables Bandwidth in CERN LHC
UCLA's Maxx Tepper gives us a brief overview of the Ocean High-Throughput processor to be used in the upgrade of the real-time event selection system of the CMS experiment at the CERN LHC (Large Hadron Collider). The board incorporates Samtec FireFly™ optical cable assemblies. The project is part of the research program of the UCLA Physics and Astronomy Department, supported by the National Science Foundation. The board receives data from 500 detectors and reconstructs particle … [Read more...]
Samtec and Achronix Technologists Detail 112 Gbps PAM4 FPGA Implementation
Readers of the Samtec blog know we are always talking about next-gen speed. Current channels rates are running at 56 Gbps PAM4. However, system designers are starting to look at 112 Gbps PAM4 data rates. Intuition would say that bleeding edge data rates like 112 Gbps PAM4 only occur in the data center. Why might that not be the case? FPGA vendors are releasing any number of new solutions featuring 112 Gbps PAM4 transceivers. FPGAs reside in a number of applications like 5G, AI/ML, … [Read more...]
A Performance Comparison of Air-Cooled vs. Immersion Cooled Connector Systems
As computing power continues to increase, air cooled systems cannot meet current thermal requirements for HPC hardware systems. Power consumption, space and performance must all be considered during system design. Immersion cooling is a fast-growing solution to economically combat system heat, noise, power consumption and compute density. Samtec’s Brian Niehoff presented “Thermal Management of HPC Hardware Architecture via Immersion Cooling” at the Exhibitor Forum at SC20. Brian’s … [Read more...]
The Challenges Of A High-Speed RF Launch Design
Samtec has provided Final Inch designs for years at no cost. Final Inch is a reference design report for a PCB launch, or break-out-region (BOR), for one of our connectors. Obviously the BOR/launch must be carefully designed to allow for the best possible high-frequency performance. As we introduce new precision RF interconnects we continue to push the limits on mmWave test boards and the design of our RF Launches. I recently spoke with Kelly Garrison, Samtec's Principal RF Engineer, about … [Read more...]
Samtec Technologists Present at Virtual Flash Memory Summit
The technical trade show calendar seems busiest in Spring and Fall. This year, due to COVID, more events are virtual. More events have been rescheduled in the Fall this year. So it seems busier than usual. Take, as an example, Flash Memory Summit. FMS usually occurs in the summer during August. This year, it will be virtual from November 10-12, 2020. What is FMS? Each year at FMS, attendees hear keynotes and the latest technology updates, forecasts, and roadmaps for the NVM … [Read more...]
Samtec to Present and Exhibit at Virtual SC20
Surprise! Another virtual tradeshow. Who knew? COVID-19 and "2020" strike again! This time we are off to SC20, which takes place November 17-19, 2020. HPC is the underpinning for many of today’s most exciting new research areas, from machine learning to artificial intelligence to quantum computing. Scientists, researchers, and data analysts from academia, industry and government agencies will be center stage at SC20. Accelerating HPC via Silicon-to-Silicon Solutions “HPC system … [Read more...]
Samtec Technical Expert Speaks at PCI-SIG Fall Virtual DevCon
Another event popular in the tech event circuit is PCI-SIG® DevCon. While DevCon events are usually in-person around the globe, this year, like so many others events, PCI-SIG DevCon is going virtual. PCI-SIG DevCons are members-driven events that provide an opportunity to learn directly from the industry’s PCIe® experts. Attendees can participate in technical trainings to gain best practices. The PCI-SIG Fall Virtual DevCon includes technical presentations from PCI-SIG Workgroup Chairs … [Read more...]
DC Block Capacitor Location: Does It Really Matter?
Samtec’s gEEk® spEEk webinars allow engineers the opportunity to interact with Samtec’s engineering leaders and SI experts on a variety of selected SI-related topics. Gustavo Blando, a Samtec Signal Integrity Architect, recently presented “DC Block Capacitor Location (Does It Matter)?” I spoke to Gustavo about his presentation and why he selected the topic, and the challenges in selecting the location of DC block capacitors. As you can probably imagine, it’s more complicated … [Read more...]
New Cable Management System Improves SI, Thermals
Samtec works with system architects in the early stages of their design to create solutions for cable management which provide even distribution of thermal load. Using ultra-low skew twinax cable to route signals over the board is a key performance enabler as signal integrity and reach continue to become ever more important in high-speed applications. I spoke to Aaron Tucker, Samtec's Engineering Director of High Data Rate Products, about the need for these cable management systems, design … [Read more...]
