New DSP Technology from Texas Instruments Brings Power and Cost Advantages to ADSL SolutionsBuilding on its industry-leading, multi-line asymmetrical digital subscriber line (ADSL) architecture, Texas Instruments (TI) will leverage the newly announced processing power and cost advantages of the TMS320C6000 digital signal processor (DSP) technology to give customers even more value from ongoing ADSL product development. Specific advances in the 'C6000 DSP core technology are reflected in the TMS320C6211 and TMS320C6202 products (see related news release - SC-98065A). For the service provider market, increased performance in the 'C6000 core technology will enable development of future ADSL chipset versions that support increased density with four or more lines per modem in central office products. For the PC/modem OEM market, the new DSP architectural features enable development of modems at lower costs, which will accelerate mass market acceptance of high-speed Internet connectivity. The 'C6000 DSP platform continues to offer outstanding programmability, scalability and performance. These features enable OEMs to keep pace with evolving DSL services and standards while developing products efficiently and economically. Combined, the processing power, cost, and flexibility advantages of TI's ADSL solutions "bridge the gap" between today's voiceband communications and emerging broadband services for the mass market. Leveraging New Performance and Cost Points for ADSL Products Based on the 'C6000 DSP core technology, TI's ADSL chipsets address both ends of the Internet access local loop. Separate chipsets are available for use in high-speed PC modems and in telecommunications end equipment such as digital subscriber line access multiplexers (DSLAMs), digital loop carriers (DLCs), and central office line cards. TI's TNETD2000 chipset for central office equipment is the only solution available today that can support multiple lines via the ADSL transceiver. Greater DSP processing power will enhance the flexibility of the TI ADSL chipsets, which enables networking OEMs to develop evolutionary DSL products based on a single platform. The new DSP enhancements also support chipsets with reduced power consumption and package space, both important factors for high-density access products that are deployed in central offices. For the very price-sensitive consumer market, the new cost options enabled by the 'C6000 DSP technology will support lower-cost ADSL modems and new standards such as G.Lite. A Superior ADSL Platform TI's ADSL chipsets combine the powerful TMS320C6000 core technology and precision mixed-signal components with discrete multi-tone (DMT), echo cancellation technology from Amati Communications. All chipsets are compliant with American National Standards Institute (ANSI) T1.413 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. TI's strengths in precision mixed-signal components and application specific integrated circuit (ASIC) technologies complement its depth in DSPs and networking chipsets. In addition to ADSL, TI offers other networking technologies for integration in access chipsets including the most widely used protocols in local-area and wide-area networks. These offerings assure product interoperability in service provider solutions that link many types of networks. TI bundles the appropriate software with the chipsets to deliver a complete, system-level solution. All TI ADSL solutions are backed by a full range of technical support, evaluation kits, and information services accessible via the Internet and a customer hotline. DSP Programmability Accommodates Rapid Technology Change The programmability of the 'C6000 DSP core technology will create a time-to-market advantage for TI customers while its flexible architecture will enable faster development of new, tailored solutions for specific market segments. 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 programmable DSP technologies give service providers and telecommunications manufacturers assurance their products will remain standards-compliant and interoperable with complementary equipment for the long term. The programmability of the 'C6000 DSP core technology, as implemented in the TI ADSL chipsets, will enable consumers to keep pace with changes in technology simply by downloading software upgrades over the network instead of buying a new modem. In addition, the TI ADSL chipset for consumer products supports "splitterless" DSL, which eliminates the need to install an external "splitter" device on the phone line, making ADSL services as simple to install and use as today's analog modems. With the 'C6000 core technology providing the foundation, TI is able to offer highly flexible and powerful ADSL chipsets that provide significant advantages over less programmable, hardwired solutions. For example, manufacturers and consumers using TI's splitterless ADSL implementation can easily upgrade via software to the G.Lite splitterless standard when it is fully defined and approved in 1999. For this capability and others, TI's highly programmable ADSL solutions allow OEMs to begin developing products that leverage new DSL technologies, then make an easy transfer to new TI chipsets as they are released. 'C6000 platform evolution also enables customers to use existing tools and software when developing new products based on new ADSL chipsets for lower overall development costs and faster time to market. TI's Networking Leadership TI's track record includes a number one market position in DSP, a number one position in the analog market, and more than 40 million DSP voiceband modem chipsets sold worldwide. By incorporating the new technology in the 'C6000 DSP core, TI is once again leveraging its voiceband leadership to excel in broadband connectivity solutions. TI's extensible, programmable ADSL architecture will continue to evolve, meeting the changing needs, standards, and cost sensitivities in both the consumer and service provider markets.
