Editor's View -- Exclusive to Electronic Design UPDATE ********************** Shocking! A 2600-Farad Capacitor By Don Tuite, Analog/Power Editor One of the best parts of being an Electronic Design editor is the opportunity to hear about new technologies, but nothing has ever caught my attention like a recent release about a bread-box-size product that contains twenty-two 2600-Farad capacitors. That's no typo. These ultracapacitors, actually Electric Double Layer Capacitors (EDLCs) to give them their proper name, have seven orders of magnitude more capacitance than the biggest electrolytic I ever soldered into a project when I was a kid. Physically, they're about the size of a tall beer can. Intrigued, I checked the Web. There's a good theoretical explanation at www.okamura-lab.com/ultracapacitor/edlc/edlc1Eng.htm. But I wanted to hear about ultracapacitors in the real world, so I called Richard Smith, who's executive vice president of strategic development at Maxwell Technologies in San Diego. Smith says the other key players besides Maxwell in the ultracapacitor arena include Panasonic, Epcos (formerly Siemens/Matsushita), and Honda in Japan, as well as Ness Corp. in Korea. If you earned your EE more than three years ago, Smith says, you won't have read about ultracapacitors in any textbook. Although the concept is more than 100 years old, until the early 1990s, nobody had solved the technical problems that would get ultracapacitors out of the lab. What is needed is an electrode with enormous surface area and an electrolyte with tiny ions. Then you need a cheap supply of those things. Maxwell solved the electrode problem in the early 1990s with a form of finely divided carbon that provides 2000 square meters of surface area per gram and an electrolyte with ions small enough to penetrate the nanoscale porosity of that carbon. Then, the company built 3-kF ultracapacitors the size of half-liter soda bottles. The only drawback was that they cost tens of thousands of dollars to make. Maxwell worked with suppliers to build capacity and yield and get the cost of raw materials down. Today's 2.7-kF ultracap costs around $50. Maxwell's goal is to get that down to $25 next year and to $13.50 by 2007. So what can you do with one? In some ways, an ultracapacitor is like a battery. But where a battery is an energy-storage device with moderate power capacity, an ultracapacitor is a power-storage device with moderate energy capacity. In other words, you can get a big kick from an ultracap, but not for very long. This is just what a lot of systems need. The generic term is "bridge power." Like the bulk capacitance in a power supply, an ultracapacitor stores and supplies power that can be delivered very quickly when needed. Ultracaps store something like 5 W-hr (18 kJ) of energy per kilogram and can discharge currents up to 1000 A at 2.5 V. A good battery might store 20 or 30 W-hr/kg but could never return it to the system at high currents. Also, an ultracap can be repeatedly charged and discharged without damage. Ultracaps are available in matchbook-size packages offering 4 F and 10 F on up to thousands of Farads. In between are such units as the D-cell, now being used in luxury automobiles to prevent sag in the bus powering the car's myriad of microprocessors when the driver turns on the steering-wheel warmer. Larger cells are also used in hybrid autos to store the energy from regenerative braking and to give the electric motor the boost it needs to get moving while the gas engine is coming up to speed. It's exciting all these years after college to find a breakthrough that increases the performance of a familiar component by literally more than a million times. Keep your eye on ultracapacitors. But don't drop your wrench across those terminals.

They allow Samtec-recommended footprints and schematics to be directly imported into complex PCB layouts. http://lists.planetee.com/cgi-bin3/DM/y/ehep0Gl4E70EmQ0BLr50A6 **************************************************************** ********************** 2. Focus On Analog ********************** ***High-Performance ADCs Require Little Power The LTC2220 family of 3.3-V analog-to-digital converters (ADCs) offers 10- and 12-bit resolutions at power consumptions of just 366 mW at 80 Msamples/s, 475 mW at 105 Msamples/s, and 630 mW at 135 Msamples/s. The devices excel at undersampling, suiting them well for communications applications such as WCDMA cellular basestation transceivers, digital predistortion power-amplifier linearization, and cable modem termination systems. The 12-bit, 135-Msample/s LTC2224, for example, features over 67-dB signal-to-noise ratio at up to 170-MHz input. It has a 775-MHz bandwidth and achieves 77-dB spurious-free dynamic range up to 250-MHz input. The slower versions and the 10-bit versions are pin-compatible with the LTC2224. These six ADCs are available now in 7- by 7-mm QFN packages at prices ranging from $6.70 to $33.92. By the end of the year, the full family of 24 devices, ranging up to 14 bits and 170 Msamples/s, will be available.

News -- From The Editors ********************** ***Digital Media Processor Handles HD Video Streams Consumer-electronics and set-top-box manufacturers looking to integrate high-definition (HD) streaming video now have a simple solution. The 720-MHz version of the TMS320DM642 media processor from Texas Instruments delivers HD video streams in Microsoft's WMV9 format at 720-p resolution. The chip can decode MPEG-4, MPEG-2, and MPEG-1 video streams. It also processes standard-definition video for the emerging H.264 format. TI additionally announced production-class devices for the DM640 and DM641, plus the 600-MHz version of the DM642. These code-compatible digital media processors are scalable across a wide range of clock speeds and memory capacities to support a broad range of applications. Prices start at $19.95 apiece in lots of 10,000 for the 400-MHz DM640. The 720-MHz DM642 costs $59.99 in 10,000-unit quantities. Samples are available now. The DM642 Evaluation Module (EVM) goes for $1995, and a full Digital Media Developer's Kit (DMDK), which includes the EVM, sells for $6495. Texas Instruments ==> http://lists.planetee.com/cgi-bin3/DM/y/ehep0Gl4E70EmQ0BLr70A8 ***RTOS, IDE Configured For PowerPC The high-reliability Integrity real-time operating system (RTOS) and Multi integrated development environment (IDE) now fit the PowerPC 970FX. The Multi C/C++/EC++ compiler can optimize code for the 64-bit PowerPC 970FX's AltiVec vector processing unit. Integrity is a POSIX.1-compatible, royalty-free operating system. It works with Multi's EventAnalyzer and ResourceAnalyzer. The Integrity System Simulator (ISIM) enables development without requiring final hardware. A DO-178B Level A certified version is available, as are extensive networking options. The Multi IDE for the PowerPC 970FX costs $5900. Green Hills Software ==> http://lists.planetee.com/cgi-bin3/DM/y/ehep0Gl4E70EmQ0BFQ60AT ***2G Actuator Allows Smaller Flat Speakers A second-generation Distributed Mode Actuator (DMA), the electromechanical component that makes flat speakers possible in small, portable applications, is 20% smaller than the first-generation units. The new transducers, which measure 22 by 7 by 3.5 mm, are up to 10 times more efficient than conventional loudspeakers and produce high-quality sound. The DMA uses a piezoelectric drive element rather than an electromagnetic one. The piezoelectric polycrystaline ceramics are smart, shape-changing materials. Applying a voltage across them alters their length, allowing them to be used as actuators. DMA prices range between $0.50 and $1.50 depedning on design, application, and quantity ordered.
