Once upon a time . . . I really don't like starting a blog out that way, but in this case, it applies. Bear with me. Like most undergrad Electrical Engineering students, I took "Introduction to Electromagnetics" my junior year. I thought it would straight forward due to previous exposure in Physics. Boy, was I wrong! No matter how hard I tried, I made no sense of some dude named Maxwell and upside-down triangles. I dropped the class in the fall semester and took it in the summer with … [Read more...]
Immersion Cooling or Convection? Connectors Exhibit Outstanding Performance In Both Cases

If you only have time for one … [Read more...]
New PCIe® Gen 4.0 With Surprise Hot Add Capability
One of Samtec's key demonstrations at SC21 featured Samtec's new PCIe® 4.0 over fiber solutions. The demo highlighted Samtec’s PCIe®-Over-Fiber FireFly™ Adapter Card (PCOA Series), developed by our partner Dolphin. The PCOA series utilizes Samtec’s PCI Express®-Over-Fiber FireFly™ Optical Cable Assemblies (PCUO series). Samtec is the only company in the world offering reset functionality and cable present sidebands in this form factor. In HPC and data centers system architectures, common … [Read more...]
Return of the gEEk® spEEk – Popular Webinar Series Continues in 2022
"Do. Or do not. There is no try." - Yoda, Grand Master of the Jedi Order Any self-respecting blog on "gEEks" should refer to Star Wars, right? In any case, the sage wisdom of Yoda continues to influence the Samtec gEEk spEEk team. Like Yoda says, the choice is to "Do". The gEEk® spEEk Signal Integrity Webinar Series returns in 2022. Samtec's gEEk spEEK team and presenters are excited to continue providing these free educational videos to our design and engineering customers. Many SI … [Read more...]
PCIe 6.0: From IP To Interconnect In High-Performance Computing
The full PCIe® 6.0 specification in nearing completion. The latest 0.9 version provides details on increased system data rate to 64 GT/s, doubling the throughput from PCIe 5.0. Additionally, the latest version further explains PAM4 encoding, FLIT-based encoding, and low-latency FEC to improve bandwidth efficiency. In this video, Ralph Page, System Architect at Samtec, walks us through a demonstration of a prototypical PCIe 6.0 AI hardware design based on the GenZ-PECFF form factor. Working … [Read more...]
New NovaRay Front Panel I/O Outperforms QSFP-DD
A new demonstration platform combines 112 Gbps PAM4 silicon from our partner Alphawave, with Samtec’s extreme performance, extreme density NovaRay® I/O front panel interconnect system. In this video from SC21 (Super Computing 2021), Samtec's Matt Burns walks us through the demonstration and explains that while they have essentially the same channel loss, the Samtec NovaRay I/O system provides twice the cable length and twice the density of QSFP-DD. Alphawave’s latest SerDes silicon … [Read more...]
OCP: New 112 Gbps PAM4 Products, Technologies
We're looking forward to the OCP Global Summit! The Keynote speakers, workshops, exhibitions, and other Summit features are back and in-person (as well as virtually), all with Covid-19 safeguards, of course. As data rate requirements approach and surpass the 112 Gbps threshold, developers are challenged with balancing increasing throughput, scalability and density demands with concerns such as power consumption, signal integrity, cost and time-to-market. Samtec helps address these … [Read more...]
