Class-D audio power amplifiers balanced just right for small LCD TVs
Product News 5/26/2004 Post a comment
Providing liquid crystal display (LCD) TV manufacturers with the feature set required to meet high efficiency audio demands, TI announced two new stereo Class-D audio power amplifiers for 17 to 23 inch LCD-TVs. The two new devices feature efficient Class-D operation, driving up to 10W of continuous stereo output power with no external heat sink.
Modern serial buses demand sophisticated level translation
News & Analysis 5/26/2004 Post a comment
Electronic design has changed considerably since the days when TTL and 5V CMOS were the dominant standards for logic circuits. The increasing complexity of modern electronic systems has led to lower-voltage logic, which in turn causes incompatible input and output levels for the logic families within a system. It's not unusual, for example, that a digital section operating at 1.8V must communicate with an analog subsection operating at 3.3V. In this article from Planet Analog magazine, a Maxim e
The Challenge of Interface Verification
Design How-To 5/25/2004 Post a comment
Designs in every industry segment are built around standard interfaces; you probably can't find a complex chip that does not have some sort of standard interface. Unfortunately for design and verification teams, these standards are all described in documents, many in the 500+ page range. Verifying these interfaces is becoming an increasingly significant challenge for chip designers. In this commentary, Denali Software's David Lin defines the solutioninterface verification.
Chip makers mull cell phones with hard drives
News & Analysis 5/24/2004 Post a comment
Cellular phones are poised to take yet another step in silicon integration by packing hard-disk drive controllers and read channels into their baseband processors. At least three companies are at some stage of exploring such designs, though several sources expressed doubts about when and at what pace hard disks will appear in cell phones. Rick Merritt reports.
Platform Challenges and Opportunities for Handsets in the Emerging Wireless Lifestyle

Listen in as Samsung's Ivan Greenberg opines what he thinks is happening in the wireless world. For example, over the next several years, wireless carriers will rollout new multimedia services at an unprecedented pace. These media-rich services will place new requirements on the platforms that power handsets. While the semiconductor technology to enable these new services has been available for some time on large PC platforms, commercialization of this technology for wireless handsets will under

AeroComm has introduced the 900MHz AC4490-1W transceiver for the growing demand for increased range among local-area industrial communication applications. It provides one watt of output allowing for data transmissions of up to 115.2 Kbps across 20 miles line-of-sight.
CANopen: The Higher Layer Protocol for Embedded Networks
Design How-To 5/12/2004 Post a comment
CANopen is a CAN-based (Controller Area Network) higher layer protocol. It was developed as a standardized embedded network with highly flexible configuration capabilities. CANopen was designed for motion-oriented machine control networks but now it is used in many various fields, such as medical equipment, off-road vehicles, maritime electronics, public transportation, building automation, and so on. This article deals with the basic protocols and services and communication objects that CANopen

Überspannungsschutz bis zu 15 kV bieten zwei neue serielle Transceiverbausteine von Intersil. Mit den beiden Full-Duplex-Bausteinen will das Unternehmen Anwendern in den Bereichen Fabrikautomatisierung, Prozesssteuerung und Netzwerksicherheit eine Alternative zu herkömmlichen seriellen Transceivern bieten – aber mit höherer Ausfallsicherheit.
Semiconductor cycle to peak next month, analyst warns
News & Analysis 5/9/2004 Post a comment
The debate rages on about the current semiconductor cycle as one analyst warned the industry will reach its peak as early as next month. It's all downhill for both the chip and IC equipment sectors starting in June of 2004, said Kevin Vassily, an analyst with market researchers Susquehanna Financial Group LLP (Bala Cynwyd, Pa.).
Converter smooths the way to direct IF sampling to 500 MHz

Editor Paul O'Shea reviews Linear Technologies 12- and 14-bit A/D converter that focuses on applications for base stations by helping to eliminate an intermediate frequency down conversion stage. O'Shea says it will do that yet still keep the distortion at a low level.
ZigBee: Wireless Technology for Low-Power Sensor Networks
Design How-To 5/6/2004 Post a comment
Technologists have never had trouble coming up with potential applications for wireless sensors. In a home security system, wireless sensors would be much easier to install than sensors that need wiring. The same is true in industrial environments, where wiring accounts for 80% of the cost of sensor installations. And then there are applications for sensors where wiring isn't practical or even possible. Gary Legg introduces a low-power wireless technology called ZigBee that is rewriting this wir
