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 solution—interface verification.

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

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
