FPGA Mezzanine Card erleichtert JESD204B-konforme Datenwandler-FPGA-Konnektivität

Heute führte Analog Devices, Inc. (ADI) auf der Messe electronica 2012 in München eine FPGA Mezzanine Card (FMC) ein, mit der Digital- und Analog-Designer dank der integrierten JESD204B SerDes (Serializer/De-Serializer)-Technologie einfacher eine High-Speed-Verbindung zwischen Datenwandler und FPGA herstellen können. Sehen Sie sich das Video (Dauer: 90sec) an und überzeugen Sie sich selbst, wie einfach und schnell das Prototyping mit ADI JESD204B Datenwandlern und FPGA-Plattformen von Xilinx Inc. sein kann: http://videos.analog.com/video/1907547501001/Rapid-Prototyping-with-JESD204B-using-FMC-and-Xilinx-FPGAs/.

Die FMC176 ist eine 14-bit, 250-MSPS, A/D Wandler FMC, die eine deterministische Latenz gemäß Unterklasse 1 des JESD204B-Standards unterstützt. Damit bietet sie die Konnektivität und Funktionalität, die für eine schnelle Verbindung mit den Kintex-7- und Virtex-7 FPGA-Plattformen von Xilinx bei verschiedenen rechenintensiven FPGA-basierten Anwendungen benötigt wird. Die FMC verfügt außerdem über zwei Analog Devices AD9129 14-bit RF D/A Wandler, die High-Speed-Kommunikationsanwendungen mit einem Datendurchsatz von bis zu 5.6-GSPS unterstützen.

„Wenn des darum geht, Mehr-Kanal-Medizingeräte oder Multi-Standard-, Multi-Carrier- Basisstations zu entwickeln, wird deutlich, dass in der heutigen Zeit die Notwendigkeit, höhere Geschwindigkeiten und Auflösungen zu erreichen, zur entscheidenden technischen Anforderung geworden ist”, so Raj Seelam, Director of Marketing bei Xilinx. „Unsere Zusammenarbeit mit Analog Devices ermöglicht es uns nicht nur auf die Wünsche unserer Kunden nach Hochgeschwindigkeits-Signalverarbeitung einzugehen, wir unterstützen dadurch auch benutzerfreundliche Entwicklungsplattformen auf Platinenebene, die eine Out-of-the-Box-Direktverbindung zwischen Xilinx FPGAs und Hochgeschwindigkeitswandlern von ADI bieten.”

Über FMC176 JESD204B FPGA Mezzanine Card

Die FMC176 verfügt über zwei AD9250, Dual-Channel, 14-bit, 250-MSPS A/D Wandler mit JESD204B-konformer serieller Ausgabedatenschnittstelle und zwei AD9129 Dual 16-bit 5.6-GSPS RF D/A Wandler.

Die 14-bit, 250-MSPS Kanäle der FMC176 können von einem internen oder extern bereitgestellten Zeitgeber getaktet werden. Es findet sich ein Trigger-Eingang, der eine individuelle Anpassung der Abtastregelung ermöglicht. Beide integrierten AD9250 A/D Wandler unterstützen eine deterministisch Latenz gemäß Unterklasse 1 und ein SYNCREF-Signal, das für eine genaue Synchronisierung aller vier Kanäle sorgt. Die FMCs erfüllen die mechanischen und elektrischen Anforderungen des FMC-Standards ANSI/VITA 57.1. Sie verfügen über einen hochpoligen High-Speed-Steckverbinder und Front Panel I/O. Die FMCs können in einer kontaktgekühlten Umgebung verwendet werden.

Die FMC ermöglicht über serielle Kommunikations-Busse eine flexible Steuerung der Abtastrate, Analogeingangsverstärkung und die Erkennung eines Messbereichsüberlaufs. Sie ist mit einem Netzteil und Temperaturüberwachung ausgestattet und verfügt über mehrere Stromspar-Modi, die nicht genutzte Funktionen abschalten oder die Karte vor Überhitzung schützen.

WebRTC services have already permeated corporate communications in the form of videoconferencing solutions. However, WebRTC has the potential of going beyond and catalyzing a new class of services providing more than calls with capabilities such as mass-scale real-time media broadcasting, enriched and augmented video, person-to-machine and machine-to-machine communications. In his session at @ThingsExpo, Luis Lopez, CEO of Kurento, will introduce the technologies required for implementing these ideas and some early experiments performed in the Kurento open source software community in areas ...

Containers are not new, but renewed commitments to performance, flexibility, and agility have propelled them to the top of the agenda today. By working without the need for virtualization and its overhead, containers are seen as the perfect way to deploy apps and services across multiple clouds. Containers can handle anything from file types to operating systems and services, including microservices. What are microservices? Unlike what the name implies, microservices are not necessarily small, but are focused on specific tasks. The ability for developers to deploy multiple containers – thous...

WebRTC has had a real tough three or four years, and so have those working with it. Only a few short years ago, the development world were excited about WebRTC and proclaiming how awesome it was. You might have played with the technology a couple of years ago, only to find the extra infrastructure requirements were painful to implement and poorly documented. This probably left a bitter taste in your mouth, especially when things went wrong.

Too often with compelling new technologies market participants become overly enamored with that attractiveness of the technology and neglect underlying business drivers. This tendency, what some call the “newest shiny object syndrome,” is understandable given that virtually all of us are heavily engaged in technology. But it is also mistaken. Without concrete business cases driving its deployment, IoT, like many other technologies before it, will fade into obscurity.
As more and more data is generated from a variety of connected devices, the need to get insights from this data and predict future behavior and trends is increasingly essential for businesses. Real-time stream processing is needed in a variety of different industries such as Manufacturing, Oil and Gas, Automobile, Finance, Online Retail, Smart Grids, and Healthcare. Azure Stream Analytics is a fully managed distributed stream computation service that provides low latency, scalable processing of streaming data in the cloud with an enterprise grade SLA.

Contrary to mainstream media attention, the multiple possibilities of how consumer IoT will transform our everyday lives aren’t the only angle of this headline-gaining trend. There’s a huge opportunity for “industrial IoT” and “Smart Cities” to impact the world in the same capacity – especially during critical situations. For example, a community water dam that needs to release water can leverage embedded critical communications logic to alert the appropriate individuals, on the right device, as soon as they are needed to take action.
With the Apple Watch making its way onto wrists all over the world, it’s only a matter of time before it becomes a staple in the workplace. In fact, Forrester reported that 68 percent of technology and business decision-makers characterize wearables as a top priority for 2015. Recognizing their business value early on, FinancialForce.com was the first to bring ERP to wearables, helping streamline communication across front and back office functions. In his session at @ThingsExpo, Kevin Roberts, GM of Platform at FinancialForce.com, will discuss the value of business applications on wearable ...
