THE WORLD LEADER IN DSP AND ANALOG
Product Bulletin
AC5 Octal-Port Central
Office ADSL Chipset
Key Features
• Industry’s only complete octal
ADSL chipset solution for central
office (CO) applications
• 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
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
(8 Mbps) or G.lite (1.5 Mbps)
ADSL. For telecommunications
equipment manufacturers and
service providers, the AC5’s
combination of ultra low power
and industry-leading integration
decreases system cost while
increasing revenue through
greater numbers of ADSL line
deployments.
Highest Integration, Lowest Power
CO Solution
With only one octal ADSL
transceiver and one octal ADSL
codec necessary for eight
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
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
modes and LineRanger™ power
optimization technology can
dynamically lower the total
chipset power for full-rate con-
nections by more than 50 percent
to less than 650 mW per channel.
Open Software Platform for
Customer Differentiation
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
