As data rates continually increase in many applications, signal integrity simulation and analysis are required to optimize the high-speed serial channel. Several design considerations are driven by signal integrity concerns. Connector selection drives performance.PCB design decisions (placement, routing, material selection, trace lengths, impedance matching, etc.) can enhance or adversely affect the performance of the high-speed serial channel.Routing breakout from the connector is often … [Read more...]
There Are No Stupid Questions – Interconnect Test Report Frequently Asked Questions
Samtec provides a wide variety of test data for nearly every product we offer. Our goal is to provide thorough, straight-forward, easy-to-access data so you can choose the best product for your application. We field countless questions about interpreting data in test reports. I asked Mark Shireman from our Engineering Support Group to list five common questions we receive about our interconnect test reports. In addition, he provides a few tips and comments to help interpret … [Read more...]
Microwave Interconnect Testing For 12G SDI Applications
Samtec and Teraspeed Consulting presented several papers at DesignCon 2016. Samtec’s Jim Nadolny (Samtec’s Signal Integrity and EMI Engineer), Keysight Technology’s OJ Danzy (Application Engineer), and Imagine Communications' Boris Nevelev presented “Microwave Interconnect Testing For 12G SDI Applications.” SMPTE ST 2082-1:2015 is the current standard for high speed digital video and requires testing to 12 GHz for video connectors. Off the shelf test solutions exist for some types of … [Read more...]
FireFly Enhances High Performance Computing In The Data Center
In the world of high performance computing (HPC), the growing trend of hardware accelerations enables higher system performance. This is accomplished by offloading non-core processing functions and system I/O management to a secondary CPU or FPGA. While co-located HPC acceleration develops a growing acceptance in high-end servers, a number of systems leverage hardware acceleration via high speed serial busses like PCIe. In some systems, the PCIe-enabled hardware accelerators are found … [Read more...]
High Bandwidth Connector Design: Full Speed Ahead
You can’t talk about technology without mentioning the need for increased bandwidth and high bandwidth connector design. On the hardware side, many say we are facing the limits of what we can do with the tried-and-true technologies that have been the foundation for technology innovation thus far -- chips, laminates, boards and elements associated with them. Addressing increased bandwidth requirements requires a systems-level approach. Those systems are defined by the hardware elements … [Read more...]

VITA 42 XMC Keeps on Truckin’
Data. Data. Data. It seems like we can’t get enough. 28 Gbps, 56 Gbps, and 112 Gbps serial channel data rates are standard or roadmap options for semiconductor, connector and optical module manufacturers. It’s almost like you need a Bugatti Veyron or Lamborghini Murcielago to get to the drug store in under 3.0 seconds for some cold medicine. Unless you are some rich Italian playboy, you probably have a sedan, a SUV, or a regular pick-up truck to run your errands. Likewise, typical … [Read more...]
How Collaborative Engineering Enables Constant Innovation
Centerlines to 0.4 mm. Gold plating that is 5μ” thick. Contact systems rated at 30 Gbps. Connectors that can handle 10,000 cycles. While our expectations are high, we all know that developing the next generation interconnect solutions requires constant engineering and manufacturing innovation. And while connectors aren’t at the top of the electronics food chain, their role is critical in the successful functioning of any electronic system. The Samtec Advanced Interconnect Design Technology … [Read more...]
BBC R+D Leverages FMC for Audio Codec Replacement
Our friends at Xilinx recently blogged about how the BBC R+D department replaced a 32-year old small rack-mount audio codec with low-cost off-the-shelf solutions customized to fit the BBC's needs. According to Justin Mitchell, principal engineer at BBC R+D, this project occurred since the original audio codec could no longer be supported due to component aging and a lack of parts. The heart of the new system is the Xilinx Zynq SoC found on the low-cost ZedBoard development kit available from … [Read more...]
Guidelines To Ensure Electromagnetic Immunity In Connectors
Electromagnetic Immunity is the ability of a system to continue functioning in the presence of electrical noise. One can imagine a scenario where an automobile drives under a cell phone tower. If the automobile accelerates to 120 mph due to coupled noise in the engine controller from the cell phone tower, one can say that the automobile is vulnerable to noise from the cell phone tower. Regulations This simple (but dramatic) example illustrates the need for immunity testing and requirements … [Read more...]
