Analog Devices offers complete audio system leveraging A2B audio bus technology
A U E
nalog Devices has introduced a full audio system that features the SHARC Audio Module (SAM) for the creation of digital audio
devices, including audio FX processors, multi- channel audio systems, MIDI synthesisers, and other DSP-based audio systems. SAM includes the dual-SHARC+ core ADSP-SC589 audio processor SoC (with an integrated Arm Cortex-A5 core) and leverages Analog Devices’ A2B audio bus technology. In addition to the main SHARC audio module board, ADI offers daughter boards to provide added functionality to the main board and expand the audio system. The Audio Project Fin board mates directly to the main board, providing MIDI input/output as well as pushbuttons and potentiometers to modify audio effects. The A2B Amplifier
Module features two high-efficiency Class-D amplifiers to output digital audio data received over the twisted-wire pair A2B bus from PDM microphones and/or serial TDM sources on the main board (or another connected A2B node). This complete audio system delivers high- fidelity multichannel digital audio with low and deterministic latency to a fully synchronised distributed audio system. The system is ideal for fast prototyping, evaluation projects, demonstrations, and educational applications. It enables users to realise a shorter time to market with a “ready to go” prototype system that provides a comprehensive hardware and software solution.

Conrad Electronic and TDK- Lambda Germany intensify collaboration
onrad Electronic and TDK-Lambda Germany agreed to further strengthen their successful long-term strategic partnership with TDK-Lambda‘s latest marketing campaign centred around DC-DC converters. The move aims to boost TDK- Lambda’s e-commerce offering and, at the same time, expand the current DC-DC converter range sold via the Conrad Sourcing Platform. “We are very happy about the strategic collaboration agreement with world-leading manufacturer TDK-Lambda Germany,” explained Kilian Braun, product manager at Conrad Electronic. “This takes the already close and successful business relationship between our companies to the next level, and underlines our expertise and excellent performance in the e-commerce sector. As a result, product designers and purchasing managers will be able to choose from a larger selection of TDK-Lambda DC-DC
converters in the short, middle and long term, and be able to find an optimal solution for their specific requirements.” “Over the past 50 years, we have been very successful globally, with our company becoming one of the leading manufacturers of industrial automation technology and medical equipment,” said Thorsten Osteroth, distribution manager at TDK-Lambda Germany. “We now want to significantly strengthen our presence and positioning within the DC-DC converter market. From talking to a large number of customers, we learnt that design engineers like to use e-commerce suppliers during early product development stages. This makes it really important to ensure quick and easy availability of the latest product versions. This is why we are strengthening our strategic e-commerce partnership and are specifically expanding our range of DC-DC converters.”

Callisto offers a flexible approach to specialist test services
nprecedented times in the aerospace and aviation industries are seeing many companies having to reduce their headcount or subcontract core capabilities in order to secure their business’ survival. Areas such as R&D and testing, which are further away from revenue generation, are often the first to feel the impact. Callisto is offering a new, flexible approach to specialist test services on an outsourced basis, with a range of products and services driven by highly experienced, best-in- class engineers but provided at a variable cost. With 20 plus years experience in Radio Frequencies and cryogenic systems, Callisto provides a full range of high precision and cost
effective cryogenic test equipment and services covering many different applications and sectors. It also offers bespoke consultancy services, widely used by organisations such as ESA, including engineering services, equipment design, system integration and thermal cycling test, from its state- of-the-art facility in Toulouse, France. A key specialism is designing and
manufacturing cryogenic LNAs to improve Ground Station Noise Temperature (NT). Callisto’s thermal vacuum cycling bench provides high precision and cost-effective cryogenic test services, using dry cryogenics with no liquid nitrogen or liquid helium. The system can cycle automatically within the defined temperature range for a large number
of cycles, usually performing between 10 and 200 cycles, though is not limited to these values. Callisto also supplies a wide range of additional specialist testing equipment and facilities for the most challenging technical projects, including particular expertise in RF measurement up to 40 GHz and RF measurement for Cryo LNA at very low noise temperature.
“Our established track record and skill-set in sat comms and cryogenic engineering means we can deliver effective solutions to the highest standards with the added advantage of being a variable cost,“ said Benoît Fauroux, managing director of Callisto. “That means we can meet client’s unique engineering needs whilst offering
Compact axial fan for modern 1U rack applications
AO Ltd has released a compact axial fan that measures just 40mm by 28mm but delivers ample airflow and static pressure necessary to cool the latest space-constrained 1U racks typically used today to accommodate high performance servers, switching power supplies and communications equipment. Developed by cooling specialist Sanyo Denki the new San Ace 40 12VDC axial fan delivers an airflow rate of up to 37.1 cubic feet per minute (CFM) and a static pressure of 2.300 Pa and easily outperforms the counter-

rotating fans designers usually choose to cool modern 1U rack applications.
According to Robert Davies, marketing manager with Sanyo Denki’s UK representative EAO Ltd, the new San Ace 40 axial fan is built with a newly developed impeller and frame construction that delivers higher static pressure, together with proprietary motor, magnet and circuitry innovations that need much less power to operate: “Space inside a 1U rack is becoming increasingly tight at engineers try to squeeze more equipment into the same space,” Davies said. “This results in a high-

pressure, high- impedance system that needs a lot of cooling airflow”. The usual cooling approach for 1U rack applications is a counter-rotating fan, but these units are space hungry and can be noisy: “The new San Ace 40 axial fan is half the volume of a counter-rotating alternative, saving 28mm of depth”, continued Davies. “Further, with this fan designers only need to accommodate half the number of fan connectors and half the number of speed sensor inputs”.
The San Ace 40 (model number 9HVA0412P3J001) provides a pulse sensor as
standard but sensor-less and lock sensor variants are available. An expected fan life of 53,000 hours at 40oC ensures maintenance-free long-term operation. The new 9HVA0412P3J001 axial fan is part of Sanyo Denki’s extensive range of San Ace brand centrifugal, counter-rotating and axial fans, all supplied and supported in the UK by EAO Ltd. Sanyo Denki products can also be sourced online from Farnell and RS.
