Chris Shelly, Samtec's RF/SI Modeling Engineer, walks us through one of two 12G SDI live demonstrations at NAB 2017. This product demonstration showcases live Return Loss testing of different connectors series per the SMPTE ST-2082-1 12G SDI single channel 4K /UHD requirements. The demonstration highlights the custom launch design that successfully allow even the more challenging right angle connector configurations to perform at this high level. With PCB terminated RF … [Read more...]
PCIe Over Fiber With Samtec FireFly
Kevin Burt of the Samtec Optical Group walks us through one of Samtec’s product demonstrations at OFC 2017. This demo features a disaggregated computing platform with PCIe® Gen 3 fabric enabled by the patented FireFly™ mid-board optical technology. This PCIe protocol is extended outside of a standard computer bus over a distance of 100 meters. Kevin also gives a quick primer on FireFly: it's a very high-density, future-proof cable assembly available in both copper … [Read more...]
Samtec Flyover Minimizes Signal Loss
Martin Rowe and our friends at EDN recently ran an article entitled "High-Speed Signals Jump Over PCB Traces." Martin begins by explaining that every time serial data rates increase, they expose problems masked at slower speeds. He goes on to summarize, "Many of those problems occur because of decreased signal integrity from losses that occur in PCB traces, vias, and connectors ... Boards used in servers and switches are often quite large and they typically have "out of the box" … [Read more...]

DesignCon 2017 — Flyover QSFP28 For 56+ Gbps Applications
A product demonstration that drew a lot of attention at DesignCon 2017 showed how Samtec FQSFP Flyover™ interconnects are used in the Keysight Reference Solution RS506 Digital Interconnect Test System. The demo has the 32 port Keysight VNA coupled to PLTS measurement software. With this system, one measurement captures all 32 ports. In this video, Jim Nadolny, Samtec’s Principle SI and EMI Engineer, walks us through the demo. Jim explains how the high-speed signals are routed … [Read more...]
Samtec Demos Flyover QSFP In Xilinx VCU118 Demonstration Board At DesignCon 2017
One of several demonstrations at DesignCon 2017 shows the variety of Samtec interconnects supporting the Xilinx® Virtex® UltraScale+ FPGA VCU118 Development Kit. Included in the kit is an FMC+ Active Loopback Card, which carries Samtec's direct attach Flyover™ QSFP28. In the Flyover QSFP28 demonstration, four GT 28 Gbps transceiver signals are generated by the FPGA and launched mid-board from the FireFly™ connector system. These 28 Gbps signals “flyover” the board … [Read more...]

Flyover QSFP28 For 56+ Gbps Applications
At DesignCon 2017, Jim Nadolny, Samtec's Principle SI and EMI Engineer, presented(1) a technical paper entitled “Design of Flyover QSFP28 (FQSFP Series) for 56+ Gbps Applications.” This white paper discusses the Flyover QSFP (FQSFP) approach for 56+ Gbps applications to overcome the limitations from the large loss on typical QSFP ports with surface mount to PCB traces. By replacing the PCB traces to twinax cables, they achieved 7 dB lower insertion loss at 40 GHz -- compared to … [Read more...]
7 Reasons To Visit Samtec At DesignCon (Number 5 Will Blow Your Mind)
DesignCon 2017 is next week in San Jose, California. If you're going to be there, here are 7 reasons to visit us at booth 717. They're all good reasons, and #5 is really cool, but it may not actually blow your mind. Sorry. Like me, you've probably seen the "sponsored articles" at the bottom of other websites. I read some research that people like to read lists, and making some kind of outlandish prediction about one of the items further improves SEO. So I … [Read more...]
