hands-on project: Firewire
unleashes the power of digital video The
IEEE-1394, or Firewire, serial bus
promises to enable a number of new
applications that rely on rich,
high-speed data streams, such as digital
video. Developing a simple digital-video
application shows the potential as well
as the limitations of the interfaces and
projects how you might use it down the
road as Microsoft makes 1394 support
standard in Windows NT, 95, and CE. --Maury Wright, Technical

Data storage in
a flash Flash
vendors are overwhelming the market with
incompatible products for data and file
storage. Look beyond the data sheets and
consider both current and future
operating requirements. --Brian Dipert, Technical

ATM switch chips
switch on Net reliability Transferring
Internet, intranet, and extranet traffic
increasingly depends on reliable ATM
switches, because a single fault in the
backbone can spiral into huge losses. To
build reliable ATM switches, redundancy
is key: Chips and system architectures
must collaborate on switches that can
survive multiple simultaneous faults. --Stephen Kempainen,

One extra
resistor fights IC op-amp oscillations
IC op amps don't like capacitive loads.
They protest by oscillating. Classic ways
of dealing with the problem usually
result in unacceptably high closed-loop
output impedance. Here's a simple way to
obtain output impedance that stays low at
frequencies out to the megahertz region. --Jimmie D Felps,

Smart-card ICs provide
unimpeachable data security
Today's contact-type smart-card ICs
provide an extremely high level of
security, and contactless types offer
supreme user convenience. Newly
introduced combined-contact/contactless
types aim to bond both features. --David Marsh,
