New DSP-Based ADSL Chipsets Available Today From Texas Instruments Increase the Speed of Internet Access
Products Include First Multi-Line Solution for Central Office End-Equipment
DALLAS (March 30, 1998) -- A new family of asymmetric digital subscriber line (ADSL) chipsets available today from Texas Instruments (TI) are the leading industry solutions that deliver the performance and programmability necessary to support evolutionary versions of DSL. TI now offers robust digital signal processing (DSP) solutions for both ends of the Internet access local loop with its new DSP-based chipsets. The chipsets are available for use in new, high-speed PC modems and service provider equipment such as digital subscriber line access mutiplexers (DSLAMs), digital loop carriers (DLCs), and central office cards.
First discussed in January, TI's ADSL products are available in sample quantities. The family of products include three chipsets that leverage a fully-programmable DSP ADSL transceiver. The TNETD2000P and TNETD2000R client-side solutions and TNETD2000C central office chipset each includes the ADSL transceiver based on the powerful TMS320C6x DSP core, a digital interface, codec and line driver. All chipsets are compliant with American National Standards Institute (ANSI) TI.413 Issue 2 and support up to 8 megabits per second (Mbps) rates for downstream communications and 800 kilobits per second (Kbps) rates for upstream communications. The TNETD2000C central office side chipset is the only solution that can support multiple lines via the ADSL transceiver.
With these new TI products, end-equipment manufacturers can now quickly deliver low-cost, high-performance ADSL modems to the consumer market. Service providers can deploy ADSL services rapidly and cost-effectively for a competitive advantage. A key advantage provided for both client side and central office solutions, programmability addresses evolving versions of DSL that will target residential applications of discrete multi-tone based (DMT)-based ADSL such as splitterless technology. This is especially important since splitterless is a version of DSL with the potential to reduce installation costs and accelerate market acceptance. DSP programmability will also create a time-to-market advantage for TI's customers while its flexible architecture will enable faster development of new, tailored solutions for specific market segments. Also, the scalability of the architecture allows modem designs to support bit rates less than 1 Mbps and up to 8 Mbps so manufacturers can address both consumer and business markets.
"TI's track record includes a #1 market position in DSP, a #1 market position in the analog market and more than 40 million DSP voiceband modem chipsets sold to date," said James Collinge, DSL product marketing manager. "With proven leadership in these areas and advanced Amati software technology TI will enable the deployment of ADSL to the mass market, provide a low total cost of ownership and bridge the gap from voiceband to broadband technology."
TNETD2000R and TNETD2000P Client Side Chipset Solutions
Designed for use in client side modems, the TNETD2000R chipset provides the core solution for both external and network termination box modems. The TNETD2000P delivers the industry's most comprehensive solution for internal peripheral component interconnect (PCI) adapter cards. The '2000P chipset includes an asynchronous transfer mode (ATM) host interface controller and robust Microsoft® Windows drivers. Complete adapter card production reference designs based on the '2000P will also be offered. These designs will help PC and modem vendors bring their products to market faster.
TNETD2000C Chipset for Service Provider Equipment
The first and only chipset on the market to support multiple ADSL lines via a single transceiver, the TNETD2000C ADSL chipset addresses critical central office design concerns. The chipset's multi-line architecture increases port densities, lowers power consumption and reduces cost-per-line. Capable of supporting two full-rate ADSL modems, the 2000C is also standards-compliant, assuring telecommunications manufacturers that their designs will be fully compatible with complementary ADSL equipment. As these standards evolve, the programmability of the TNETD2000C chipset ensures that the designs will stay both standard-compliant and interoperable.
Leveraging TI DSL Technology and Amati Expertise
All three ADSL chipsets combine TI's TMS320C6x core, the world's fastest DSP, and precision mixed-signal components with DMT echo cancellation technology from Amati Communications. Recently acquired by TI, Amati Communications has been the pioneer and leading ADSL developer as well as a significant contributor to ANSI and International Telecommunications Union (ITU) standards. Collectively, TI now holds elected positions in the TI.413 Issue 2 standards body, G.dmt and European Telecommunications Standards Institute (ETSI). TI will also leverage the field trials in the USA, Canada, Europe and Asia started by Amati in 1995. Additionally, TI is a core technology provider to the Universal ADSL Working Group (UAWG), a consortium organized by Microsoft, Intel®, and Compaq® to promote interoperability of DSL consumer products.
Pricing and Availability
Samples of the chipsets are available from TI today. Evaluation kits will be available in second quarter of 1998 while volume production and TNETD2000P reference designs are planned for the third quarter. The suggested resale pricing for the TNETD2000C is $95 in volume quantities of 25,000. Suggested resale pricing is $76 for the TNETD2000P and $65 for the TNETD2000R also in quantities of 25,000.
