Data centre interconnect drives optical module advances

The huge growth in demand for video, cloud services and social networking is changing almost everything about the way the networks are built and used, not least the interconnect technologies within data centres and the ‘top of rack’ network switches that shift packets between the optical internet boxes – or Data Centre Interconnect (DCI) – and the servers that store and process the data.

Intel’s Programmable Systems Group takes its first step towards an FPGA based system in package portfolio

Speaking in 2012, Danny Biran – then Altera’s senior VP for corporate strategy – said he saw a time when the company would be offering ‘standard products’ – devices featuring an FPGA, with different dice integrated in the package. “It’s also possible these devices may integrate customer specific circuits if the business case is good enough,” he noted.

Irish company pioneers the development of 94GHz RF circuits for a range of applications

It wasn’t too long ago that GHz frequencies were regarded as exotic; few applications took advantage of that part of the spectrum as technology was not only difficult, but also expensive. That meant that military dominated the few applications there were. The Brimstone missile is believed to use 94GHz technology for targeting purposes, rather than the lasers used in previous missiles.

The Brexit debate: should we get out or ‘remain, reform and revitalise’

Could the UK pulling out of the European Union pose as big a threat to the global economy as a ‘hard landing’ in China? That was the claim made recently by the Organisation for Economic Co-operation and Development’s (OECD) chief economist Catherine Mann. According to Mann, a vote to leave the EU will not only impact the UK, but would also have a significant impact on the global economy.

RF tests are the basis for V2X

Wireless technologies are being used to connect vehicles, but in order to ensure that messages are received accurately, developers need to adhere to minimum standards.

The benefits of using non-isolated DC/DC converters

The DC power requirement for electronic industrial equipment often consists of a 24V high power output and a number of lower power, lower voltages. Traditionally these requirements have been achieved by a number of power architectures, depending upon the amount of system power required.

Power supply standby voltage and off-load power draw

The use of a Standby Voltage on computer power supplies became widespread when the ATX specification was published in 1995. It enables a computer to be put into a low power consumption mode without fully powering down the processor, allowing a quick response when activated again. This was achieved by using a remote on/off signal to turn off the outputs, but still supplying a small amount of power to the processor from an independent voltage. This ‘Standby Voltage’ is always present even if the main outputs are inhibited using the remote on/off.

Technology developers could ease the burden on the NHS

If you think telemedicine and telehealth are relatively new concepts, think again. Amazingly, the idea was first floated in the US in 1925 by Hugo Gernsback. His concept – the teledactyl – combined wireless communications, haptics and a form of viewscreen. It would, he contended, allow doctors to examine their patients and to use instruments remotely.

Solar generation is powering up, but faces a range of materials issues

In 2015 the global installed capacity for photovoltaics hit 180GW and the European Photovoltaic Industry Association reckons more than 0.5TWwill be generated from solar cells by the start of the next decade. Government incentives intended to stave off climate change and falling costs have helped push up production, but one of the ironies of a technology meant to change the way we harness energy is the amount that it takes to produce each square centimetre of photon-harnessing panel.

The surprising differences between ARM MCU cores that appear to be identical

There are many reasons why the ARM Cortex-M series of processor cores has come to dominate the market for 32bit microcontrollers. Across the many varieties of Cortex-M cores, design engineers can choose from an array of performance, power consumption and communications capabilities, allowing them to find an ARM based MCU which will be suitable for almost any application. And, by standardising on the Cortex-M family, OEMs not only benefit from a common instruction set, but also from an ecosystem of libraries, tools and firmware with which thousands of embedded engineers are already familiar.

Addressing the need for ultra-small ambient light sensors in wearable products

In today’s wearable health and fitness market, where consumer electronic backlight displays continue to get thinner, having an ambient light sensor (ALS) capable of being integrated into the thinnest backlight displays is becoming ever more important to designers of these devices. The proliferation of cell phones and the demand for a better user experience has driven a higher adoption rate of ALS in touchscreen smartphones. In these display management applications, automatically controlling the backlight intensity with an ALS ensures the best possible user experience while extending battery life.

Linear Technology's Bruce Hemp and James Wong bring ease of use to microwave radio design

Bandwidth is rapidly expanding in the next generation wireless access to cope with the ever-increasing Internet traffic. At the same time, the current available spectrum in use simply cannot support the needed bandwidth. So higher frequency spectrums are being evaluated for suitability. Multiple options are considered, ranging from unlicensed 5.8GHz terrestrial stations, to fleets of low-orbit satellites that blanket the earth. The path to higher bandwidth lies with new higher frequencies to deliver on that promise. New mixers with improved performance will be needed. A new mixer, the LTC5549 from Linear Technology, is launched to support this effort.

Addressing key challenges in automotive infotainment test with the NI PXI Platform

Automobiles have experienced rapid growth in the amount of in-vehicle electronics in recent years and a key area where these electronics are playing a vital role is in the infotainment system of the vehicle. In fact, the infotainment systems have become somewhat of a hub for a number of functions of the vehicle, and represent where both large amounts of information and driver entertainment are converging. Not only do they continue to blur the line between the driver’s mobile phone and the car for entertainment purposes, but there is also an overlap with important components of advanced driver assistant systems (ADAS).
