Industry View -- Exclusive to Electronic Design UPDATE ********************** Backward Compatibility Is Important In Open-Standard Backplanes By Justin Moll, Director of Marketing, Elma Bustronic Architectures like the VMEbus have been so successful largely due to their continued performance enhancements while maintaining backward compatibility. Over the years, the steps have been incremental for these types of backward-compatible open-standard (BCOS) technologies. But today, new innovations can take VME and CompactPCI to revolutionary levels...

VARTA PoLiFlex ultra-slim batteries provide excellent performance in extreme temperatures and exhibit virtually no swelling. The technology is intrinsically safe; the product is currently available. http://news.electronicdesign.com/t?ctl=275C2:484C79 **************************************************************** *******************Live on ElectronicDesign.com***************** Free Webinar: Measurements and Analysis for Switch-Mode Design Thursday, April 27, 2006 at 2:00pm ET This seminar covers the measurements of interest for designers of switch-mode power-conversion circuits and devices. We'll review the acquisition of voltage and current, their relationship in switch-mode power-conversion circuits, and the analysis of power-device switching losses, conduction losses, safe operating area, and dynamic on-resistance. Register today! http://news.electronicdesign.com/t?ctl=275BB:484C79 **************************************************************** ********************** 2. Focus On Analog ********************** ***Audio Amp Outputs More Power Using Less Board Space A tiny audio amplifier from National Semiconductor increases output power while shrinking package size by 30 percent over most existing amplifiers. According to the company, the LM4995 Boomer 1.3-W mono Class AB audio amplifier is housed in the world's smallest micro surface-mounted device (SMD) package, which measures 1.25 by 1.25 mm with a 0.4-mm pitch. It targets cell-phone hands-free and ringer functions. Operating on a single 5-V supply, the LM4995 can drive an 8-ohm speaker load at a continuous average output of 1.3 W with less than 1 percent total harmonic distortion plus noise (THD+N). It offers a power-supply rejection ratio (PSRR) of 74 dB at 217 Hz and a low quiescent power-supply current of 1.6 mA for longer battery life in portable systems. Pricing is $0.65 each in 1000-unit quantities. The amplifier is available now in a lead-free, nine-bump micro SMD package. An evaluation board is also available.

News -- From The Editors ********************** ***RoHS Catalog Identifies Old Parts With New Names A distributor of electronic components and test equipment has released an interactive RoHS-compliant catalog to help ease the transition to the EU directive. Newark InOne's Web-based catalog features 40,000 RoHS-compliant products. The tool lets users view both new and old part numbers of a particular product. This is important because many manufacturers have been changing part numbers as they release RoHS-compliant versions of their products. The catalog also serves as a guide, with sections dedicated to understanding the directive, analyzing parts' lists for compliance, ensuring accuracy, and information about purchasing RoHS-compliant products. The free catalog can be found on the company's Web site.

The module utilizes 72 standard 512-Mbyte memory devices to create a product that meets JEDEC specifications for RDIMM dimensions (30-mm core). According to the company, the four-rank memory organization can deliver better system performance than a two-rank memory module of the same capacity. The module is based on Staktek's ArctiCore Technology, which is designed to improve thermal, mechanical, and electrical performance in high-speed applications. Utilizing a double-sided, multilayer flexible circuit with embedded interconnect technology folded around a rigid thermal core, ArctiCore increases the available area for mounting devices while enhancing thermal management, reliability, and thinness. Licensing and manufacturing services for the 4-Gbyte, four-rank ArctiCore modules are currently available.

Gore withstands extreme conditions such as widely fluctuating temperatures, extreme moisture, and large amounts of environmental contaminants. A tough metal housing delivers durability in harsh and explosive environments. The Gore Vent provides protection and pressure equalization for electrical enclosures, outdoor electronics, domestic appliances, and other products containing electronic components. Gore protective vents allow air to pass freely through housings, so they virtually eliminate the stress caused by sudden changes in temperature and pressure that can compromise gaskets or housing seals. These vents also provide the advantage of easy access to sensitive electronics for maintenance without enabling contaminants such as water, chemicals, oil, or dust to enter the housing. The vent is available in a wide variety of sizes and configurations. W.L.

Read Technology Editor Bill Wong's latest EiED Online column, "Building A SAS RAID File Server." Adaptec's 335SAS enclosure and 4805SAS RAID controller are the centerpieces to this high-performance server that Bill has built. It also incorporates AMD's FX-60 dual-core Athlon 64 processor on ASUS's latest K89N-LR motherboard. It's cool and fast. http://news.electronicdesign.com/t?ctl=275BC:484C79 ********************** TAKE A POLL! Researchers have created a nanotube-laced paint that blocks, or greatly attenuates, RF signals. Should it be used to block the ringing of cell phones in places like theaters? -- No, that violates my Constitutional rights -- Maybe, but it could be hazardous in emergency situations -- Yes, I hope it's used on a wide-scale basis -- There are better ways to deal with cell-phone noise Vote at Electronic Design ==> http://news.electronicdesign.com/t?ctl=275C9:484C79 ****************************************************************
