Da Radioteleskope sich nunmehr in Echtzeit-Digitalinstrumente gewandelt haben und ein großes Spektrum abdecken können, bedarf es sehr leistungsfähiger Signalverarbeitungs-Cores, um eine ausreichende Auflösung des Spektrums zu erzielen,” erläuterte Simon Underhay, Technical Sales Executive bei RF Engines. Mit einer derartigen Auflösung können Astronomen 'sogar die kleinsten Veränderungen oder flüchtigen Ereignisse innerhalb des Spektrums erfassen.”

For the Catalyst 4500 family, Cisco is offering a 48-port 10/100/1000 card for $7,495, or a 48-port 10/100 card for $6,495.

In the stackable Catalyst family, Cisco has introduced a version of the 3750 switch with integrated POE support. The switch is offered with two or four fiber ports, with an option of a standard Layer 3 software package (QoS, advanced security, and RIP routing), or an enhanced software package (standard features plus multicast routing and policy- based routing), in a price range of $4,795 to $10,490. A brand-new fixed-port switch in the 3000 family is the 3560, offering POE support in standard 24-port and 48-port models.

To expand the ways that POE features can be used, isco is offering a special 1U Redundant Power System for its stackable switches. Shalita emphasized that the RPS 675 is not an uninterruptible power supply, but is intended to provide 675W of power in failover mode to up to six Cisco devices.

For its chassis-based 4500 family, Cisco also is showing customers how to use dual power supplies in bridged mode, as well as in traditional redundant modes.

Woburn, MA, Feb.16, 2004 – Skyworks Solutions, says it has unveiled the world's smallest quad-band, integrated RF subsystem for GSM/GPRS handsets. The tiny subsystem delivers all the core functions required for a cell phone to make and receive calls in a single compact package.

Skyworks achieved the world's first sub-250 mm2 quad-band RF subsystem by combining an industry-first 6 x 6mm quad-band RF transceiver with the company's existing 8 x 10mm RF transmit front-end module. The new 6 x 6mm SKY74117 direct conversion transceiver (DCR) is the smallest of its kind, incorporating all required functionality in single package that is roughly one-quarter the size of a postage stamp. The compact DCR transceiver is based on technology that Skyworks pioneered in 2002 and has since refined through two product generations and an industry-leading 25 million shipments, to date.

The subsystem's SKY74117 RF transceiver builds on the innovations Skyworks pioneered with its first DCR. The use of an advanced direct down-conversion architecture eliminates the need for intermediate frequency (IF) components and cuts the number of external components required to build a radio subsystem by more than one-half. This reduces the overall bill-of-materials costs and frees valuable board space.

The SKY74117 RF transceiver is paired in the subsystem with Skyworks' SKY77500 iPAC transmit front-end module to create a complete, integrated solution in an extremely compact footprint. The SKY77500 module combines the company's industry-leading iPAC power amplifier (PA) module and switch functions into a single low-cost laminate-based multi-chip module (MCM). The MCM is 40 percent smaller than alternative solutions and delivers superior handset talk and standby time. Key features include a high-performance quad-band PA with current sensing power control, high-linearity transmit/receive switches, and all associated filtering, duplexing and control functions. No external matching components are required.

Skyworks' quad-band RF subsystem supports GSM850, EGSM900, DCS1800 and PCS1900 cellular data services. It leverages the company's leadership expertise in PA module, switch and DCR technology. All functional blocks are fabricated with proven advanced process technologies to optimize performance and power efficiency.

A panel at the Design, Automation and Test in Europe conference on Thursday (Feb. 19) warned that SLD tools remain out of the mainstream in part because system makers aren't convinced that new tools will provide the performance increase needed to justify the investment.

SLD tools are too expensive, and companies don't want to spend the money,” said EDA expert Simon Davidman.

As a result, SLD market forecasts remain guarded. Third-generation ESL tools providing full hardware and software co-design and co-verification are expected to arrive by 2006, according to estimates by market researchers Dataquest. By that time, the market is expected to be worth $250 million.

If the right tools arrive, the number of SLD designs and engineers could take off. Many are expected to come from existing IC design groups. However, We don't know for that's going to happen,” said Dataquest senior analyst Gary Smith.

European companies have moved fastest to embrace SLD tools along with Japanese firms. Consumer electronics companies have been most aggressive, said Mark Milligan, marketing vice president at CoWare. Only a handful of U.S. companies have so far embraced the design technology. U.S. companies have been extremely slow” to adopt SLD, Smith said.


We are appalled that Mr. Niknejad would disclose Silicon Laboratories' trade secrets to Axiom Microdevices,” said Dan Artusi, president and CEO of Silicon Laboratories, based here.
