Murata SAW resonators for SRDs

Murata's latest family of SAW resonators is designed for short range devices (SRDs) operating in the ISM300 and ISM400 bands, and achieves +/-50ppm tolerance. Because of its tight tolerance, the SARCC series of SAW resonators helps designs comply with the latest ETSI frequency error standard.

The thermal coefficient of the three millimetre square package has been reduced by almost 50% to 0.016ppm/ deg C (typical) and the resonant loss has been improved by approximately 1dB to 1.5dB (maximum), compared to previous generations of SAW resonator.

The range is offered with tolerance of either +/-50kHz or +/-50ppm, compared to the +/-75kHz offered by previous generations.

Resonators in the SARCC series come in two types, each named using a different suffix: part numbers suffixed -KX are intended for the consumer electronics applications and are also suitable for some automotive applications such as RKE (remote keyless entry) systems. Part numbers suffixed -TX are full automotive grade (AEC-Q200) devices, suitable for applications such as TPMS (tyre pressure monitoring systems).

The new family, which covers all the most requested frequencies, is available in industry standard 3.0x3.0mm size, 6-pin ceramic packaging and is backward compatible with older devices.

2.4GHz wireless chip has own MCU

Nordic Semiconductor has introduced its smallest 2.4GHz wireless device, the nRF24LE1 which integrates a 2.4GHz transceiver core (the nRF24L01+) and a mixed signal 8-bit microcontroller with flash memory for ULP wireless applications.
The device has an enhanced 8051 mixed-signal MCU core featuring fewer clock cycles per instruction than legacy 8051 devices. Most instructions need just one or two clock cycles leading to an average performance improvement of x8 using the MIPS benchmark.
This performance and the chip's 16kbyte of on-chip flash plus 1kbyte of SRAM enables it to run both the RF protocol stack and application layer.

The chip is available in a 4x4mm QFN package.
A ULP 32kHz crystal oscillator provides timing for low report rate synchronous protocols and a 16MHz RC oscillator provides fast start-up times from idle. The 32kHz oscillator can provide timing accurate enough for higher report rate protocols without requiring an external crystal.
A security co-processor supports AES encrypted wireless communications.

Intersil ISL59450 multiformat video multiplexer with integrated sync separator

Intersil's ISL59450 multiformat video multiplexer with integrated sync separator has six Composite, four S-Video and four Component video inputs enabling simultaneously switching of a number of video signals in different formats.

Another feature is that two of the Component input channels can be configured for RGB signals with separate horizontal and vertical syncs. This allows for handling of PC video signals often used in multimedia and home-theatre applications.

The device features integrated programmable anti-aliasing filters that provide the ability to program the corner frequencies to specifically address the video standard being used.

Two universal sync separators extract the timing signals from input signals, which will be needed further down the signal path to display and manipulate images. This, along with two active output channels per input group, supports picture-in-picture (PIP) functions.

The ISL59450 also features programmable output gain control. To support very high resolution signals it can be configured to bypass the filters and provide 275MHz of bandwidth.

Revolution in the cellphone industry by the introduction of Iphone

The Apple iPhone has brought about a revolution in the world of consumer electronics. In 2007 it was Steve Jobs who mentioned it in his key address at Macworld Conference & Expo.

Initially in the hands of Job it looked like a slim black triangle lacking in animation. Then the touch of Jobs on its screen was like a magic wand. All on a sudden the stodgy lifeless black rectangle came to life - the surface began to throb with animation. The fingers of Job slid around the screen moving an arrow to unlock the phone. To many it is this that is most amazing feature of the marvel that is the iPhone - the connection between the finger and the image on the screen.

There are plenty of other features. The iPhone is more akin to a palmtop computer rather than the cellular phone. As with the typical smart phones the iPhone can be used to make as well as receive phones. One can view movies, hear music, browse through the web as well as operate e-mails. Messages too can be sent like the conventional SMS. Inside it there is a camera for taking photographs. Pictures can be transferred from the computer to the iPhone by the use of special software. The iPhone allows for viewing of maps and satellite information from Google.

A modified edition of Macintosh OS X operating system can also be used on Apple computers. iPhone allows interaction with these applications. Icons for each of these operations are displayed on the screen of the iPhone. It automatically controls battery power and the security devices. Similar to the computer it is amenable to multi tasks.

The iPhone dispenses with the use of a mouse or a typical keyboard. It uses buttons and controls. These appear on the screen. The touch screen of iPhone is distinct from others in many ways. Usually when the screen is touched a contact is made with a slim stylus with a point. But the iPhone makes use of the fingers. Multiple touch points are detected simultaneously. This many of the touch screen devices in the market cannot do. With each passing day touch screen technology is becoming more sophisticated and prevalent. Microsoft recently introduced Surface. It is the latest in touch-sensitive computer interfacing. This will lead to a mouse-free age of the computer.

The Apple iPhone is unique by itself as regards multi touch interfacing. Apple is incorporating the touch-screen at the reverse of the iPhone rather than on the front. For enforcing this magical touch device wherein the iPhone responds to the touch of the fingers the technology that is used makes use of multi layered capacitive layers.

Its circuit arrangement is such that it can respond to changes at each point right through the grid. Each point on the grid, therefore, generates own signals when touched. It then relays that to the processor inside the iPhone. Thus the phone responds to multiple touches. It is the fingers alone that bring to life the iPhone.

Thus the most important parts are the processor and the software of the iPhone. The processor makes use of the software to understand the data that comes through - that is find out the nature of each touch. The processor measures the difference between the point of start and end of the touch. The processor then relays the instruction to the programme.

With only one button on the front surface the Apple iPhone is weaving this magic. Pressing it one goes to the main screen where there are icons for using the four primary functions.

Future Nanoelectronics May Face Obstacles

When the size of the components approaches the nanometer level, all information will disappear before it has time to be transferred.

"Our findings throw a monkey wrench in the machinery of future nanoelectronics. At the same time, it's a fascinating issue to address just how we might be able to prevent the information from being lost," says Mattias Marklund, professor of theoretical physics at Umeå University in Sweden.

The electronics we know in our computers today is, as the name suggests, based on the transfer of information with the help of electrons. Using electrons has allowed us to shrink the size of computer circuits without losing efficacy. At the same time, communication with the help of electrons represents a rather slow means of transmission.

To alleviate this problem, light can be used instead of electrons. This is the basis of so-called photonic components. While the transfer speed in photonics is extremely high, the size of the components cannot be shrunk to the same level as 'ordinary' electronics.

For a number of years, so-called plasmonic components have proven to be a possible way around the dilemma of electronics and photonics. By combining photonics and electronics, scientists have shown that information can be transferred with the help of so-called plasmons. Plasmons are surface waves, like waves in the ocean, but here consisting of electrons, which can spread at extremely high speeds in metals.

The findings now being presented by the Swedish-American research team show that difficulties arise when the size of such components is reduced to the nanometer level. At that point it turns out that the dual nature of electrons makes itself felt: the electrons no longer act like particles but rather have a diffuse character, with their location and movement no longer being clearly defined. This elusive personality leads to the energy of the plasmon being dissipated and lost in the transfer of information. For nanocomponents, this consequence is devastating, entailing the loss of all information before it can be transferred.

"The effects we have discovered cannot be fully avoided, but the behavior of the plasmons might nevertheless be controlled by meticulous component design that takes into consideration the quantum nature of the nanoscale. It's our hope that continued research will provide a solution to this problem," says Mattias Marklund.

It may be time for you to consider cutting the (phone) cord

If you haven't rethought your home phone service, now might be the time. Intense competition among companies and technologies has traditional standalone phone service from a Ma Bell descendant seemingly going the way of the dodo.

The dodo, a flightless island bird, became extinct in the 17th century because of human behavior and the introduction of new predators. Ditto, perhaps, for traditional landline phone service. Landline phone service is high quality and extremely reliable. But phone companies are losing customers daily to competing companies and technologies.

Bill Kula, a spokesman with Ma Bell descendant Verizon Communications Inc., said the company is experiencing an 8 percent to 9 percent decrease per year in landline phones. But he said the traditional landline has a future in the home telecommunications mix. Surveys show customers like the reliability of a landline and the security of knowing it has full emergency 911 capabilities. ''The wired telephone is not going away with the dinosaur,'' he said. ''It will continue to be a versatile part of the society for decades to come.''

Time will tell, but here are examples of predators and human behavior invading the habitat of traditional phone companies. They might just save you money:
Bundles. Deals abound, with phone and cable companies duking it out to sign customers to their triple-play services--TV, Internet and phone. Landline phone service has become such a commodity that it's almost a throw-in. It often includes unlimited long-distance calls and a wide host of features, such as call-waiting and caller ID. If you already subscribe to pay TV and Internet access, you might save by moving all your services under one roof.

Wireless. Cutting off landline service and using only a wireless phone is becoming more common as people become used to calling people, not places. A generation ago, callers would dial up a place, such as a home or an office because phones were tied to buildings. Today, wireless phones are associated with individuals, so people call other people. As they become commonplace, it's harder to justify duplicate landline telephone service.

Before cutting the cord, make sure you have adequate reception throughout your home and enough minutes on your wireless plan to handle calls at home and on the go. Several wireless carriers have introduced unlimited calling plans, many for about $100 per month. They often are of dubious value, said Allan Keiter, president of wireless comparison site For $100 per month, consumers already could receive 2,000 minutes--33 hours--with free nights and weekends, and free mobile to mobile. Few people use that much. Unlimited plans are aimed at dangling the concept of unlimited calling at customers on $80 plans with about 1,300 minutes so they trade up.

VoIP and MagicJack. Consumers have many choices for using their broadband Internet access as a phone line, using a technology called voice over Internet protocol, or VoIP. Maybe the most interesting and easiest is from, which offers phone service with unlimited long-distance, voice mail, caller ID, call waiting and other features for $19.95 per year.

For an additional $20, you must buy a matchbox-sized device that plugs into the USB port on your computer. You plug a phone line and phone into the other end of the device. Software loads onto your computer automatically and you get a dial tone. So, to get started, the device plus a year's service costs $39.95, and you never receive a monthly bill.

MagicJack inventor Dan Borislow said the company has sold more than 1 million of the devices so far. He assumed his customers would be business travelers, perhaps taking the device abroad to call home for free. Not so.

''They're people on budgets, people trying to save money,'' Borislow said. The average age of users is 55. The other major group of customers wants to dump their landline but their cell phone doesn't work well in the house, he said. They use MagicJack as their landline, often plugging a cordless phone base into the MagicJack line and adding multiple handsets throughout the house.

Drawbacks of MagicJack include not being able to keep your existing phone number. You'll receive a new one. And you must have the computer on to place and receive calls. If it's off, incoming calls go to voice mail. Borislow said the company is working on solutions to both of those disadvantages.

And while MagicJack works flawlessly for many people, others seem to have problems. The service is only as good as your broadband Internet connection. Voice quality can range from as good as a landline to as poor as a cell phone with a weak signal. Use the 30-day money-back guarantee to try MagicJack before canceling landline service.

Other Internet-based phone services, such as Skype and Vonage, can also use regular telephones and can be cheaper than landline phone service. Several traditional phone companies also offer VoIP service.

    From noise-cancellation for frequent travelers to affordability for customers on a budget, Sony today unveiled three new Walkman® players (series S, E and B) that have something to offer nearly every customer segment.

    “Whether the fit and finish, the engineering or the integration of unique technologies, each of these new series has different points of appeal,” said Mitch Li, product manager for Walkman players in the Digital Imaging and Audio Division at Sony Electronics. “These new Walkman players satisfy the need of consumers who don’t want to sacrifice sound quality for the digital music and MP3 experience.”

    S-Series Walkman Players

    The top-end, format-friendly Walkman S-series broadens options for enjoying tunes from multiple sources, including many download stores and personal music collections. The supplied Content Transfer software even simplifies “drag and drop” transfer of non-DRM music, videos, podcasts and playlists from online music services to Walkman players. If you’re migrating your personal collection of ripped tracks from another MP3 player, there’s no need to re-rip all your tunes from your CDs.

    Support for popular audio and video codecs is enhanced because the S-series Walkman devices play Windows Media Video (WMV) files with DRM, allowing you to enjoy rights-protected movies and video clips from other media collections.

    Additionally, the S-series Walkman players are the first MP3 players with Sony’s SensMe™ Channels function, which automatically creates channels that can align with a user’s preferences. Based on Sony’s SensMe Channels function, the S-series players analyze a user’s music collection and suggest channels based on each song’s speed, mood and rhythm. They create a choice of 11 themed channels from upbeat pop to emotional ballads.

    In-Flight Noise Cancellation

    Whether commuting, flying high or just listening to music at home, the new S-series Walkman players help diminish background noise while improving your overall listening experience. The top-end S-series Walkman players feature integrated active noise cancellation with supplied 13.5mm EX noise canceling headphones and an accessory cable that extends the noise canceling functionality of the device. On airplanes, travellers can – for the first time – connect the S-series player directly to a plane’s audio video system with the included accessory cable and enjoy regular in-flight entertainment with the bonus of high-quality noise cancellation.

    Just 7.5mm thin, the super-light S-series is the slimmest Walkman player in any of the new series. It has a bright, high-contrast 2-inch QVGA LCD screen (measured diagonally) that has an ultra-quick response time, with smooth playback at up to 30 frames per second and selectable horizontal/vertical viewing. The interface can be personalized with the user’s choice of 10 pre-installed wallpaper images or their favorite digital photo.

    E-Series Walkman Players

    The E-series combines high-quality video and audio performance to create the perfect device for enjoying favorite photos and video clips. Like the S-series, all E-series models are format friendly, easily playing back ripped tracks from your personal music collection, music store downloads and rights-managed video clips. Non-DRM files can be transferred by “drag and drop” from online music services to Walkman players.

    Support for popular audio and video codecs is enhanced because the E-series Walkman players can also support Windows Media Video (WMV) with DRM, allowing rights-protected movies and video clips from other media collections.

    B-Series Walkman Players

    The affordable entry-level Walkman B-series player offers the high-quality sound that users have come to expect from Sony. The ultra-portable devices can connect to your PC’s USB port for easy “drag and drop” file transfers. Like all other Walkman models, open support for Windows Media Audio (WMA) and MP3 codecs enables users to buy, copy and manage music to fit their needs.

    The stylish design is enhanced by an illuminator that pulses in time with the music when the bass button is pressed. The device has an FM radio for enjoying favorite stations and a voice recorder that’s great for capturing memos, shopping lists or random thoughts while you’re on the move.

    Battery Life

    The battery life is up to 40 hours of music playback for S-series, up to 45 hours for the E-series and up to 16 hours for the B-series. The battery life is up to 10 hours of video playback for S-series, up to 8 hours for the E-series. The battery life is also up to 30 hours of audio playback for the S-series when the noise-cancellation feature is activated. Actual battery life may vary upon usage patterns, product settings, battery and environmental conditions.

    Sony’s Open Platform Means More Choice

    The E- and S-series Walkman players support an open platform, providing more choices for downloading and managing music and video collections online. The devices can support security-enhanced Windows Media Audio (WMA), as well as non-secure AAC, linear PCM and MP3 music formats plus JPEG files for photos, in addition to the WMV with DRM, AVC (H.264/AVC) Baseline Profile and MPEG-4 video codecs.

    Researchers Develop New Technique For Fabricating Nanowire Circuits

    Spearheaded by graduate student Mariano Zimmler and Federico Capasso, Robert L. Wallace Professor of Applied Physics and Vinton Hayes Senior Research Fellow in Electrical Engineering, both of Harvard's School of Engineering and Applied Sciences (SEAS), and Prof. Carsten Ronning of the University of Jena, the findings will be published in Nano Letters. The researchers have filed for U.S. patents covering their invention.

    While semiconductor nanowires---rods with an approximate diameter of one-thousandth the width of a human hair---can be easily synthesized in large quantities using inexpensive chemical methods, reliable and controlled strategies for assembling them into functional circuits have posed a major challenge. By incorporating spin-on glass technology, used in silicon integrated circuits manufacturing, and photolithography, transferring a circuit pattern onto a substrate with light, the team demonstrated a reproducible, high-volume, and low-cost fabrication method for integrating nanowire devices directly onto silicon.

    "Because our fabrication technique is independent of the geometrical arrangement of the nanowires on the substrate, we envision further combining the process with one of the several methods already developed for the controlled placement and alignment of nanowires over large areas," said Capasso. "We believe the marriage of these processes will soon provide the necessary control to enable integrated nanowire photonic circuits in a standard manufacturing setting."

    The structure of the team's nanowire devices is based on a sandwich geometry: a nanowire is placed between the highly conductive substrate, which functions as a common bottom contact, and a top metallic contact, using spin-on glass as a spacer layer to prevent the metal contact from shorting to the substrate. As a result current can be uniformly injected along the length of the nanowires. These devices can then function as light-emitting diodes, with the color of light determined by the type of semiconductor nanowire used.

    To demonstrate the potential scalability of their technique, the team fabricated hundreds of nanoscale ultraviolet light-emitting diodes by using zinc oxide nanowires on a silicon wafer. More broadly, because nanowires can be made of materials commonly used in electronics and photonics, they hold great promise for integrating efficient light emitters, from ultraviolet to infrared, with silicon technology. The team plans to further refine their novel method with an aim towards electrically contacting nanowires over entire wafers.

    "Such an advance could lead to the development of a completely new class of integrated circuits, such as large arrays of ultra-small nanoscale lasers that could be designed as high-density optical interconnects or be used for on-chip chemical sensing," said Ronning.

    The team's co-authors are postdoctoral fellow Wei Yi and Venkatesh Narayanamurti, John A. and Elizabeth S. Armstrong Professor and dean, both of Harvard's School of Engineering and Applied Sciences; graduate student Daniel Stichtenoth, University of Gottingen; and postdoctoral fellow Tobias Voss, University of Bremen.

    The research was supported by the National Science Foundation (NSF) and the German Research Foundation. The authors also acknowledge the support of two Harvard-based centers, the National Science Foundation Nanoscale Science and Engineering Center (NSEC) and the Center for Nanoscale Systems (CNS), a member of the National Nanotechnology Infrastructure Network (NNIN).
