Key Features
• Industry’s only complete octal
ADSL chipset solution for central
office (CO) applications
AC5 Octal-Port Central
Office ADSL Chipset
• Supports industry’s highest port
densities:
- <400 mW per port excluding
line transceiver
- <1.3 sq. inches per port from
tip/ring interface to data
interface
• First open-software ADSL
platform enabling customer-
specific value-added features
and functions
• Supports VoDSL as well as Voice-
over ADSL (VoADSL), through
standard Utopia and PCM
interfaces
• Powered by Amati technology
only 250 milliWatts (mW) per
channel for the digital device, 150
mW per channel for the codec
and 900 mW for the line trans-
ceiver. Combined, the complete
AC5 solution, including the line
transceiver, consumes only 1.3 W
per modem for a complete, full-
rate ADSL modem from Tip/Ring
to the Utopia-II interface. In
addition, TI’s advanced power

optimization technology can
New AC5 board layout represents 8 channels of full-rate ADSL.
New from Texas Instruments
(TI), the AC5 octal ADSL chipset
once again redefines the potential
of central office (CO) Asymmetric
Digital Subscriber Line (ADSL)
equipment. Leveraging TI’s four
previous generations of advanced
programmable DSP-based ADSL
products, this highly integrated
solution achieves the lowest
power consumption per channel
of any industry offering. The AC5
doubles the number of channels
currently available, providing
eight-channels of full-rate
combination of ultra low power
and industry-leading integration
decreases system cost while
increasing revenue through
greater numbers of ADSL line
deployments.

More than just high download
speeds, the world of broadband
is built on value-added services.
The AC5 ADSL chipset is the
world’s first to offer an open
software platform that allows
manufacturers and intellectual
property providers to integrate
standards-compliant modems,
the AC5 chipset features the
industry’s smallest modem area,
requiring <1.3 sq. inches per
modem from Tip/Ring to the
Utopia-II interface. The AC5
also delivers the industry’s lowest
power consumption, requiring
