Texas Instruments Inc. and Motorola Broadband Communications Sector are
joining forces to speed the delivery of Data Over Cable Service Interface
Specification 1.0-, 1.1- and 2.0-certified cable modems to the broadband-cable
The deal calls for Motorola to incorporate TI's complete DOCSIS system into
its 'SURFboard SB4220' cable modem.
TI's complete DOCSIS system integrates the physical (PHY) and
media-access-control layers of the open-system-interconnect reference model,
with a high-performance communications processor and peripherals for networking
and communication applications.
The SURFboard SB4220 will also incorporate TI's A-TDMA (asynchronous
time-division multiple-access) advanced PHY capability specified in the
CableLabs DOCSIS 2.0 standard.
Motorola has been in the cable-modem business for eight years, and it has
shipped roughly 8 million units into the market.
