Samtec has been analyzing launch design optimization techniques to improve signal integrity in high frequency test applications for many years, and continues to build upon initial findings for 224 Gbps test systems. In this blog, Part 1 of the series "How to Improve Signal Integrity for 224 Gbps Test Systems," we'll be examining a few key principles for improving signal integrity from the test instrument to the device under test (DUT). These principles are outlined in Samtec's recent published … [Read more...]
Ultra Micro Printed Circuit Board (PCB) Connectors for Reliable, 56 Gbps PAM4 Data Transfer
The need for printed circuit board (PCB) connectors to have increased mechanical reliability combined with high-speed performance to 56 Gbps PAM4 in an ultra micro form factor continues to gain traction in extremely rugged data applications. A few examples include industrial IOT, robotics, drones, and military and aerospace. However, with proliferating advancements in the automotive industry, the need for reliable high-performance ultra micro interconnects for automotive has escalated. … [Read more...]
Keysight and Samtec Demonstrate New 112 Gbps PAM4 Connectivity
Samtec and Keysight teamed up at DesignCon 2024 to showcase a multi-domain template testing Samtec’s high-performance NovaRay connector system. This live signal integrity product demonstration incorporates two different types of test instrumentation. First, we see a Keysight four-port, 53 GHz VNA (Keysight P5028B) testing a Samtec NovaRay mezzanine connector system (NVAM, NVAF products) at 112 Gbps PAM4. We also see a Time Domain Reflectometer (Keysight DCA-Z, N1000A) with a six-picosecond … [Read more...]
Connectors for HPC and Supercomputing
Our modern industrial world depends on raw materials. Whether oil, steel or cotton, raw materials have been of huge importance to the development of the industriaized world. While these physical products remain as vital as ever, the modern era has brought us a new raw material in the form of data. As consumers, we are familiar with data as we use our smartphones and computers. However, the volume of data that is created by modern systems is on a scale that many of us might struggle to … [Read more...]
From AI to SI: Samtec Participates on Two Upcoming Webinars
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...]
How to Design Component Launches Faster
Designing and optimizing a breakout region (or component launch) for a connector can be challenging. It often requires multiple back and forth iterations and analysis to adjust variables. Samtec’s new SIBORGTM (Signal Integrity Breakout Region Guru) is a free tool that works with Ansys HFSS 3D Layout to generate, visualize, optimize, and develop PCB package and component breakout regions (BORs), enabling Samtec customers to design component launches faster. SIBORG was initially intended to be … [Read more...]
New Samtec RF Test and Measurement Solutions At DesignCon 2024
Samtec demonstrated many high-performance RF test and measurement solutions at DesignCon 2024. In this video, David Beraun, Samtec's RF Product Manager, takes a quick look at some of those high-performance RF test and precision RF products. This first demonstration incorporates Samtec Bulls Eye®, a proven test and measurement cabling solution. A Keysight N5247B PNA-X network analyzer, with extension heads, evaluates the performance of the DUT up to 110 GHz. The DUT is the Bulls Eye system, … [Read more...]
