| 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

| 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
