Amati and TI Announce Agreement To Jointly Develop And Market Discrete Multi-Tone Technology For ADSL Modems Based on TI DSPsTI and Amati To Provide DMT Expertise in Software Implementation, Using TI High Performance, Fixed-Point DSP Components for Flexible ADSL Designs
San Jose, CA, October 16, 1996 Amati Communications
Corporation (NASDAQ: AMTX) and Texas Instruments Incorporated
(NYSE: TXN) today announced an agreement to jointly develop Asymmetric
Digital Subscriber Line (ADSL) core technology based on TIs TMS320
Digital Signal Processors (DSP). The combination of both TIs and
Amatis Discrete Multi-Tone (DMT) expertise and TIs position as
the worlds leading DSP solutions supplier will further enable
the development of new technology for the design of ADSL interface
devices.
Amati is a technology leader in high-speed
ADSL implementation using the DMT standard as approved by the
T1E1 committee. The technology was first developed by Amati, who
holds patent rights on key design elements. DMT enhances ADSL
by enabling transmission at speeds up to 6.144 Mbps downstream
and up to 640 Kbps upstream for ADSL connections using existing
twisted-pair copper lines without interfering with regular telephone
service.
"This alliance with Amati represents
a significant step toward our future involvement with the growing
ADSL market," said Terry Riley, Director, business development
Access business unit within Texas Instruments. "TIs and Amatis
design capabilities, combined with TI DSPs and analog front-end
chips, will enable the design of ADSL modems that are more cost
effective and more flexible than alternative designs."
"The combination of TIs DSPs and Amatis
ADSL expertise are expected to lead to future ADSL modem and access
system designs that will be able to offer - through the use of
effective software design - more features per modem and even more
modems per silicon IC," said James Steenbergen, President
and CEO of Amati.
The agreement calls for the combined effort
by both companies to develop ADSL solutions. Amati and TI will
provide the core ADSL software based on their respective DMT technology.
TI will then market the software along with their DSP and analog
front-end components for customers implementing ADSL system interfaces.
In addition to the key efforts between the two companies in the
development of ADSL software, TI will also be a key partner for
Amati in their system development. With the growing need for Ethernet
and ATM access to be integrated with ADSL, TIs experience in other
data communication technologies and protocols will enable Amati
to support such requirements. TI will provide software and integrated
circuits for communication interfaces compatible with their DSP
components. Amati will then have use of these core designs for
system development and access products.
TI has been developing DMT algorithmic expertise
since 1978 and has made major strides in complexity reduction.
This expertise enables DMT ADSL modems to be implemented in fully
programmable DSP platforms, while still remaining highly cost
competitive.
Amati has been developing their core software
technology since 1992 and recently released the first commercial
implementation of an ADSL modem capable of up to 8 Mbps downstream
data transmission while supporting 640 Kbps in the return direction.
Amati believes that alternative ADSL solutions are only capable
of much slower data rates and are less robust in terms of real
world telephone copper wire conditions. Amatis technology has
been tested throughout the world in both video and Internet access
applications. "TIs DSP technology plays a key role in many of todays advanced interfaces and these interfaces will be needed to assure that future ADSL systems meet the desired network architecture," said Steenbergen. "An effective combination of ADSL and data technologies is an important part of the expansion of ADSL services throughout the world. The agreement between Amati and TI assures future ADSL solutions will be constructed using the latest DSP technology and the most advanced ADSL software implementation, two important factors required for full-service network availability of ADSL in the future," added Steenbergen.
