RS Components sign agreement with Adapteva to deliver energy-efficient open-source computing platform
RS Components (RS) has signed what it describes as a significant distribution agreement with Adapteva, producer of the Epiphany multicore co-processor and developer of the popular Parallella-16 board. The partnership will bring the Parallella board directly to customers in Europe and Asia and will enable quicker, easier access to this energy-efficient technology.
Parallella was introduced to the industry through a successful Kickstarter crowdsourcing campaign with the objective of opening up access to supercomputing. The open-source project now has thousands of users around the globe in one of the industry's most active programming communities. The open- source single board computer includes the Epiphany III 16 core co-processor on the board alongside the Xilinx Zynq Z7000 dual core ARM processor. The credit card sized device can be used as a development platform, embedded
engine, teaching platform or research tool and is easily scalable by clustering boards to create a mini-supercomputer for advanced parallel computing applications. "As a leading electronics distributor, RS has the experience and reach to provide wider access to the Parallella board around the globe," said Jonathan Boxall, Global Head of Semiconductors at RS Components. "After the initial success of Adapteva we are committed to help expand that success to a much broader range of users via our worldwide network."
"Adapteva is changing the way that people do computing as traditional approaches are nearing the end of their power efficiency," said Andrea Olofsson, CEO and Founder of Adapteva.

"Parallella puts new capabilities in the hands of the novice and the expert. We are making parallel programming an everyday, low cost, accessible technology."
The Parallella board is available in three models and can be purchased from RS for same-day despatch from the company's global distribution centres.
New Amphenol military connectors depend on integrated EMC filters made by MPE
Amphenol, one of the world's largest manufacturers of interconnect products for the military, commercial aerospace and industrial markets, has worked together with Liverpool-based MPE Ltd to develop a range of ground-breaking connectors which come with integrated EMC filtering. In conjunction with Amphenol, MPE has produced the Rhino range of filtered
as military and electric drive vehicles, aircraft and communications base stations. Accordingly the new Rhino 38999 Series of high-power, single-pole, connectors has been developed to meet those requirements.
While Amphenol recognised that many military vehicle applications have a need for EMC suppression it had traditionally been using a box-type filter which adds unnecessary costs and took up too much space.
The challenge for both companies was to deliver a high degree of suppression within the envelope of a filtered connector that provides mechanical compliance to MIL-DTL-38999 Series III and EMC suppression compliance to DEF STAN 59-411 and MIL-STD-461.
The Rhino 38999 Series which is now available comes with a standard range of cost-effective MOTS (Military-Off-The-Shelf) filters suitable for EMC suppression of
connectors that are intended to deliver not only a high level of EMC suppression performance but can do so within very tight physical constraints. According to Amphenol there is distinct
trend towards increased power and voltage requirements on applications such

under vibration. The large surface area of the socket contact also results in a very low contact resistance, enabling much higher current ratings compared to other power contact designs.
according to Amphenol. Assemblies can be supplied with C or Pi
filter circuits and can also include high- power varistors that provide protection against EMP and lightning strikes. The assemblies are supplied with pin contacts at one end and sockets at the other. The use of RADSOK contacts creates an electrical interface that exceeds typical interconnect requirements via a hyperbolic socket contact construction. The latter distributes normal forces over a high percentage of the mating surface, to ensure a smooth and even engagement force with exceptionally high performance
Silicon Labs is looking to simplify the complexity associated with designing clock trees for a wide range of Internet infrastructure applications including high- speed networking, telecommunications and data centre equipment. Its new Clock Tree Expert tool is intended to enable embedded developers to generate sophisticated, streamlined clock tree block diagrams within minutes, simplifying system design, reduce the bill of materials (BOM) count and speeding time to market.
Networking and telecom equipment designers are under pressure to deliver best-in-class products at competitive prices, as a result the timing component selection and clock tree design are more important than ever because timing ICs provide low-jitter timing references for high-speed 10/40/100G data applications and can greatly impact system-level performance. So when specifying clock trees, hardware designers must ensure critical jitter performance parameters are met with sufficient margin but with the minimum number of timing components. Choosing the optimal combination can be a daunting and time-consuming task as a result.
Leveraging Silicon Labs' DSPLL and MultiSynth technologies, the new web- based Clock Tree Expert tool recommends the optimal combination of highly integrated, low-jitter, frequency-flexible clocks and oscillators required to consolidate timing BOM into the fewest number of components to the design engineer.
Intuitive and easy to use, users simply enter the required frequencies, number of clocks and desired signalling format, and the tool generates a recommended clock tree in seconds using the minimum number of timing components. Experienced users can also use the tool's "Build Your Own" environment to design clock trees to their exact specifications. The Clock Tree Expert then guides the user to find the optimal timing ICs, save and share clock tree designs, generate a BOM list and order samples. "While growing demand for high-speed
Internet infrastructure equipment is driving the complexity of timing architectures, we're committed to making clock tree design as fast and easy as possible for developers," said James Wilson, director of marketing for Silicon Labs' timing products. "Our Clock Tree Expert tool automates the process of creating and customising clock trees and accelerates the hardware development process."
