| Cover Story | |
| Line drivers and receivers push signals through cable's reality | Cable driving is an old art. New applications such as ADSL/HDSL, cable
modems, LANs, and high-resolution video require drivers and receivers that
provide increased power, bandwidth, fidelity, and tolerance of line
uncertainties. —Bill Schweber, Technical Editor |
| Communications Products Special Section | There's nothing hotter these days than communications. What better time, then, to give you a look at some products that just might fit the bill. |
| Design Features The hottest new technologies and the latest design techniques to help you work efficiently and effectively. | |
| Available bit rate bridges the gaps in ATM networks | ATM networks have yet to live up to promises of bandwidth on demand and
quality of service. A new ATM Forum standard and forthcoming ICs offer hope,
how-ever, and a new flow-control scheme, ABR, could optimize bandwidth usage in
typical ATM networks. —Stephen Kempainen, Technical Editor |
| Time flies when you're analyzing it | Timing analysis has come a long way from the old pencil-and-calculator
days. Modern timing analyzers provide detailed timing information for your
design. Now, you must decide whether a static or a dynamic analyzer better fits
your needs. —Clive "Max" Maxfield, Intergraph Computer Systems |
| Echo-canceller design ensures hands-free, high-fidelity telephony | In the past, system designers programmed general-purpose DSP µPs for
high-quality echo cancellation. Now, dedicated hardware eliminates the need for
software development, shortens the design cycle, and reduces system cost and
power consumption. —Jamal Sarma, Oki Semiconductor |
| Ten ways to bulletproof RS-485 interfaces | Despite its widespread use, RS-485 is not as well understood as it should
be. However, if you invest a little time on familiarizing yourself with the bus
and pay attention to 10 aspects of your application, you'll find that designing
rock-solid implementations is easy. —John Goldie, National Semiconductor |
