Analog Devices To Provide DSP For 3Com 56k Modems - Integrated DSP & mixed-signal solution enables
modem system-on-a-chip -
PR Newswire, Wednesday, December 03, 1997 at 12:57
NORWOOD, Mass., Dec. 3 /PRNewswire/ -- Analog Devices, Inc. (ADI) today
announced that 3Com will use a new ADI chip which integrates all the analog
and digital signal processing components of a 56K modem. This single-chip
solution is a custom design for 3Com (NASDAQ:COMS), the world's leading modem
maker.
Today's U.S. Robotics(R) modems require five discrete integrated circuits
(ICs). ADI will integrate these chips onto a single silicon die -- in essence,
a 56K modem-on-a-chip. ADI's expertise in mixed-signal and DSP integration
will enable 3Com to produce a modem that consumes less power than currently
available designs. The IC will include 3Com's x2(TM) 56K* technology, which
provides high speed downloads from over 1200 Internet Service Providers
offering x2 service worldwide.
With this development, 3Com includes ADI as one of its suppliers for
designing and manufacturing digital signal processors (DSPs) customized for
high-speed modem applications.
"Analog Devices provides 3Com with a valuable supplier for integrated
DSPs," said Jerry Devlin, vice president and general manager of 3Com's
Personal Communications Division.
"By integrating all analog and digital signal processing components onto
one chip, we go to market faster, with modems that feature lower power
consumption. Additionally, this new DSP will make it easier for our products
to comply with FCC regulations."
