`Central Office ADSL Chipset
`Providing End-to-End Solutions
`for High-Speed Communications
`
`Key Benefits
`• Fifth-generation ANSI T1.413 Issue 2
`compliant modem chipset
`• Industry’s first multi-line central office
`architecture
`• Highly programmable architecture
`• Ultra-high-performance, echo-cancellation
`based architecture
`
`With more than 100 times the
`performance of today’s analog
`modem technology, Asymmetric
`Digital Subscriber Line (ADSL) is
`revolutionizing the remote access
`industry. ADSL is a new broad-
`band communications technology
`that allows telephone companies
`to deliver multi-megabit commu-
`nication performance directly to
`the home. And best of all, ADSL
`delivers this high-speed perfor-
`mance over existing copper tele-
`phone infrastructure—all while
`allowing traditional voice services
`to coexist without interruption.
`ADSL technology is enabling the
`delivery of high bandwidth, multi-
`media rich applications like
`streaming video, video conferenc-
`ing, interactive tele-gaming and
`ultra-fast Internet access.
`As the first in a new generation
`of DSL solutions, TI’s TNETD2000C
`central office chipset provides
`designers with a highly program-
`mable, high-performance solution
`for the ADSL central office market.
`TI also offers the TNETD2000P
`and TNETD2000R client-side
`ADSL chipsets, providing design-
`ers with end-to-end ADSL solu-
`tions. The chipsets utilize TI’s
`revolutionary 1600 Millions of
`Instructions Per Second (MIPS)
`TMS320C6x technology and
`world-class mixed-signal exper-
`tise to provide the industry’s most
`powerful and most programmable
`ADSL solutions. As the market
`evolves, TI will add to these initial
`offerings with solutions tailored
`to meet the needs of specific DSL
`market segments. For instance,
`TI will leverage its existing net-
`working expertise by customizing
`the ADSL chipset architecture
`with networking specific periph-
`erals. Key peripheral technologies
`
`include 10/100 Ethernet, 1394,
`USB, ATM, HDLC and PCI.
`TI’s position in the DSL market
`has also been greatly strength-
`ened by the recent purchase of
`Amati Communications, the
`world leader in DSL technology.
`Largely recognized as the DSL
`pioneer, Amati brings to Texas
`Instruments four previous gener-
`ations of ADSL modem expertise
`and extensive real-world field
`trial experience. By leveraging
`this experience and expertise, TI
`is in a unique position to deliver
`the world’s most cost-effective,
`high-performance DSL solutions.
`
`The Architecture
`At the heart of the TNETD2000C’s
`architecture is the power of ’C6x
`DSP technology. This technology
`provides an incredible amount of
`processing power for DSL modem
`implementations, and TI has har-
`nessed it in developing two
`extremely high-performance yet
`highly programmable chipsets.
`Some of the more advanced fea-
`tures of the architecture include:
`
`Highly Programmable Architecture—
`The fully programmable ’C6x-
`based ADSL transceiver facili-
`tates quick and easy software
`upgrades, code updates and even
`
`future standard implementations
`such as the upcoming G.Lite
`splitterless standard.
`
`High-performance Architecture—
`Leveraging the raw processing
`power of ’C6x technology, the
`TNETD2000C chipset offers the
`industry’s highest throughput,
`longest reach and most robust
`ADSL modem performance. The
`chipset also benefits from Amati’s
`four previous ADSL modem gen-
`erations and more than 20 real-
`world field trials. TI adds to the
`inherent performance of its chip-
`set architecture by implementing
`echo cancellation to separate the
`upstream and downstream chan-
`nels. This greatly improves the
`overall performance of the
`modem. And for interoperability,
`the chipset will also work with
`existing Frequency Division
`Multiplex-based (FDM) products.
`
`Multi-line Architecture—
`Once again taking advantage of
`the processing power of the ’C6x-
`based ADSL transceiver, the
`TNETD2000C is the first and
`only chipset on the market that
`can support multiple ADSL lines
`via a single transceiver. This
`increases port densities, lowers
`power consumption and reduces
`cost-per-line.

`Programmable Management
`Interface—
`The fully programmable manage-
`ment interface supports flexible
`network management by provid-
`ing access to configuration, per-
`formance, statistics and control
`information. This interface is pro-
`vided in C-compliant source code
`that runs on an external micro-
`controller or host processor. By
`providing the source code for this
`interface, end customers can
`completely customize the man-
`agement code base to suit their
`particular application.
`
`The Chipset Devices
`The TNETD2000C consists of
`four devices and the necessary
`software (both datapump and
`management interface software)
`to implement a fully compliant
`ANSI T1.413 Issue 2 ADSL
`modem. TI’s central office ADSL
`chipset offers designers every-
`thing they need to take end prod-
`ucts from concept to production,
`saving both design time and
`money by giving OEMs a single
`resource for all of their design
`requirements. The four devices
`include:
`• TNETD2100 Digital Interface—
`Programmable serial interfaces
`provide simple and clean stan-
`dards-compliant data interfaces
`to the chipset. In order to sup-
`port asynchronous transfer
`mode (ATM) implementations,
`each serial interface features a
`Byte mark pin. The TNETD2100
`is packaged in a 208-pin PQFP.
`• TNETD2200 ADSL
`Transceiver—Based on the
`high-performance TMS320C6x
`DSP technology, the completely
`programmable ADSL trans-
`ceiver provides the necessary
`computationally intensive digi-
`tal signal processing required
`for MIPS-intensive ADSL
`modem operation. The
`TNETD2200 is packaged in a
`352-pin BGA.

`
`• TNETD2021 Codec—The
`TNETD2021 central office
`codec is a high precision
`mixed-signal device that pro-
`vides the analog-to-digital
`(A/D) and digital-to-analog
`(D/A) conversions and associ-
`ated filtering required for ANSI
`T1.413 Issue 2 modems. The
`TNETD2021 is available in a
`100-pin TQFP.
`• THS6002 Line Driver—The
`THS6002 provides the high-
`speed line drivers and the
`receive circuitry required to
`drive the ADSL line. The device
`is available in TI’s patented
`PowerPadTM package, reducing
`the size of the device and
`greatly improving its thermal
`dissipation characteristics.
`The THS6002 is packaged in a
`20-pin Flatpack.
`
`Benefits for Central Office
`Applications
`The TNETD2000C ADSL chipset
`addresses critical central office
`design concerns, including stan-
`dards compliance, programma-
`bility, low power and increased
`port density. The chipset is fully
`ANSI standard T1.413 Issue
`2-compliant, assuring telecommu-
`nications manufacturers that
`their designs will be fully compat-
`ible with complementary ADSL
`equipment. And as these stan-
`dards evolve, the programmabil-
`ity of the TNETD2000C chipset
`ensures that the designs will stay
`standard-compliant and inter-
`operable as well. TI achieves
`increased port density, lower
`power consumption and reduced
`cost-per-line by leveraging the
`multi-line architecture of the
`ADSL transceiver. Using this
`inherent performance advantage,
`the transceiver has the raw
`computational power required to
`implement multiple lines of full-
`rate ADSL.
`
`.TEXAS
`INSTRUMENTS
`
`Currently, both the Digital
`Interface and ADSL transceiver
`support up to two full-rate ADSL
`lines. As the core ’C6x technology
`becomes even faster, the trans-
`ceiver will support more full-rate
`ADSL lines, further increasing
`port densities while continuing to
`reduce power consumption and
`cost-per-line. The next-generation
`ADSL chipset will be able to sup-
`port four full-rate ADSL lines. In
`addition to full-rate implementa-
`tions, the ADSL transceiver can
`support between two to three
`times as many less computation-
`ally intensive G.Lite lines as full-
`rate lines. For instance, the same
`ADSL transceiver that supports
`two full-rate lines can support
`between four to six G.Lite lines.
`The exact number of G.Lite lines
`supported depends on the final
`form of the G.Lite standard.
`
`Central Office ADSL EVM
`Designers can begin building
`tomorrow’s remote access appli-
`cations today with TI’s central
`office ADSL Evaluation Module
`(EVM). The kit gives designers
`everything they need to fully
`evaluate the simplicity and power
`of TI’s ADSL solutions.
`
`For More Information
`DSL represents more than a new
`technology. It is a fundamental
`new approach to remote access
`communications that uses existing
`infrastructure to deliver incredible
`new bandwidth and incredible
`new applications. For this con-
`stantly changing environment, TI
`offers the industry’s most power-
`ful and flexible solutions. If you
