Readers of the Samtec blog are familiar with the benefits of FMC and FMC+. These popular interfaces define a compact electro-mechanical expansion interface for a daughter card to an FPGA baseboard or other device with re-configurable I/O capability. VITA 57.1 has been around for some time. It supports 10 full-duplex transceivers running at 10 Gbps. The new VITA 57.4 standard defines two new connectors. Combined, they offer 32 full-duplex transceivers running at 28 Gbps. New … [Read more...]
Rugged, High Bandwidth Interconnects Save Space On PCB
Edge Rate®, one of Samtec’s most popular high speed, high bandwidth interconnect systems, also saves space on your PCB. Edge Rate is both the name of the contact system and the product family. The contact system is designed for high speed, high cycle, rugged applications. With some connectors, the mating edge of the contact is the cut edge of the pin (but not Edge Rate!). If you look at the edge of the pin under a microscope you may see micro burrs and edges. This reduces the life of … [Read more...]
5 Meter, 56 Gbps Long Reach Backplane Cable Assembly For Rack to Rack Applications
Long Reach Backplane Cable This live demonstration from DesignCon 2019 shows how Samtec's ExaMAX® backplane connector, combined with Samtec Flyover® technology, achieves high density and very long reach. Here, the reach is five meters for a rack-to-rack interconnect system. In this video, Samtec's Gustavo Blando walks us through the topology and discusses system performance. Samtec Flyover systems can be used in mid-board applications to achieve next gen speeds with longer reach … [Read more...]
112 Gbps Interconnect Increases Reach Between the ASIC and the Front Panel
In this demonstration at DesignCon 2019, J.R. Bonnefoy (a Systems Engineer at Samtec) explains how Samtec Flyover® offers a 112 Gbps high-density escape from the system ASIC to the front panel. Signal Path A Credo Pelican II SERDES generates 31-bit PRBS data at 112 Gbps PAM4 data rates. Signals travel from the Credo test board, through precision RF cable assemblies, to a Samtec NovaRay cable assembly SI evaluation board. The signals then route through the NovaRay board, to the … [Read more...]
English Guy (Who Thinks He’s James Bond) Demos 56 Gbps System With 5.8 Tbps Throughput
Samtec’s Active Product Demonstrator proves 56 Gbps PAM4 based systems are fully realizable today. It’s a state-of-the-art prototype combining high-performance interconnects from Samtec and bleeding edge Credo silicon. All interconnect and silicon shown are available. The Demonstrator internally generates over 100 independent channels of signal data using Credo mixed-signal 56 Gbps PAM4 SERDES Bald Eagle silicon. Each signal generated is QPRBS 31, 56 Gbps PAM4 data, equivalent to 5.8 Tbps of … [Read more...]
112 Gbps PAM4 Backplane Cable: Higher Performance, Less PCB Complexity
In this video from DesignCon 2019, Scott McMorrow walks us through a live demonstration showing how NovaRay® Cable assemblies offer extreme density while enabling 112 Gbps PAM4 performance. In combination with an ExaMAX® Backplane Cable assembly, the traditional backplane architecture is retained, but with higher performance targets and lower PCB complexity. Samtec Flyover® systems can help extend signal reach and density to achieve next gen speeds by routing signals via Eye Speed® ultra-low … [Read more...]
Submersible Optical Transceiver For Super Computing
Next generation super computers, quantum computing, AI engines, and high-performance emulation systems are all evaluating the benefits of liquid cooling. Liquid cooling removes the heat more efficiently than airflow, eliminates the noisy, power-hungry fans used in traditional air-cooled systems and enables denser, more-efficient processing boards and systems. One technology holding back the adoption of liquid cooling has been the lack of optical transceivers which perform … [Read more...]
10 Reasons To Visit Samtec At DesignCon 2019
DesignCon is one of my favorite conferences/exhibitions because there is so much going on. DesignCon has the latest state-of-the-art design methodologies, applications, technologies, and tremendous networking opportunities. Booth 737 -- the Samtec booth -- is the epicenter of the show; it's where all of the important people hang-out (that's why you won't see me there). I don't have room to list everything going on at the Samtec booth, so I've selected 10 items that I think are the most cool. … [Read more...]
112 Gbps PAM4 Samtec Flyover™ Live Demonstration
112 Gbps Samtec Flyover™ Demo Samtec’s Ralph Page walks us through a live demonstration of a Samtec Flyover™ system which enables 112 Gbps PAM4 performance. The Credo CDR generates two ports of 31-bit PRBS data at 112 Gbps PAM4 data rates. The signal travels from the Credo Pelican II SERDES test board through precision RF cable assemblies, to a Samtec Flyover™ QSFP-DD SI Evaluation Kit. This cable assembly, approximately 12” (30.5 cm) long, uses Samtec 34 AWG Eye Speed® Ultra-Low … [Read more...]
Rearchitected OCP Wedge Switch Using Samtec Flyover™
In this video from SC18, Jignesh Shah of Samtec’s High Speed Connectivity Group walks us through a demonstration of a rearchitected Open Compute Project (OCP) wedge switch. By rearchitected we mean it utilizes Samtec Flyover™ high-speed cable assemblies to achieve next gen speeds by routing signals via ultra-low skew twinax cable instead of through the PCB, as in conventional architecture. The system has a 12.8 Tb Marvell ASIC with 32x QSFP-DD ports on the front panel, sending signals at … [Read more...]
