Cuts Power Consumption and Footprint by One Third
Infineon Technologies AG (FSE/NYSE: IFX), a leading supplier of broadband access semiconductor solutions, today launched GEMINAX PRO, the industry’s highest-integration and lowest-power ADSL2+ chipset. Consisting of a 16-channel ADSL2+ Digital Front End (DFE) and a 4-channel Analog Front End (AFE), with integrated low-power Class D line drivers, the GEMINAX PRO chipset reduces power dissipation, footprint and overall system costs by up to 30 percent, in comparison to other chipsets currently available. Additionally, Remote Units (RUs) - typically constrained by power, area and battery back-up requirements - which incorporate the new Infineon chipset will also benefit from significant operational cost savings. Also, in environments where power dissipation values are restricted by standards, for example, the North American Network Equipment Building System (NEBS) standard, operators can now exploit real estate in the central office more efficiently.
High power dissipation of currently available ADSL2+ line drivers limits the integration to two channels per device. Infineon’s revolutionary switched-mode (“Class D”) line driver technology reduces the power dissipation of the line driver by 50 percent to less than 350 milliWatts per channel, allowing the integration of four line drivers and AFE channels into a single device. In contrast to ordinary linear devices available on the market, Class D devices use Pulse Width Modulation (PWM) technology to generate a higher efficiency analog signal that dramatically reduces power dissipation in the output stage. Class D amplifiers, widely used in audio applications, are restricted to low frequency range of few kiloHertz. On the other hand, ADSL2+ requires an operating bandwidth of 2.2 MHz. A multitude of technological innovations introduced by Infineon have made it possible to overcome this challenge without sacrificing performance.

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
