Cover Story
- 31st Annual Microprocessor Directory Field Guide
New processor offerings continue to include targeted, integrated peripheral sets that span all architecture sizes. - FROM EDN EUROPE: Is ZigBee ready for the big time?
ZigBee/802.15.4 promises much: simple-to-implement, inexpensive wireless networks for low-data-rate applications that can run for extended periods from battery power. Can it deliver?
Design Features
- DDS simplifies polar modulation
Basic modulation mathematics and DDS (direct digital synthesis) provide designers with an all-digital technique for generating polar-encoded carrier signals. - Analysis of board layout helps cure jitter problems
In a design in which you must reduce tight timing, routing all timing-sensitive lines in buried stripline layers minimizes one source of jitter and lowers the overall required timing budget.

How It Works
- Flat speaker delivers volumes of sound
Contrary to conventional understanding, a flat speaker can be both a product panel and a source of high-quality sound.
Tech Trends
- Heat wave: FPGAs confront increasing, evolving power consumption
Innovative FPGA designs can moderate the escalating power problem at the expense of performance, but a technology shift may prove to be your best bet.
