No Wires Needed For TI's Home-DSL Trio (02/26/01, 6:58 p.m. ET) By Patrick Mannion , EE Times Targeting the home and small office, Texas Instruments Inc. is wrapping its physical-layer expertise, its voice- and packet-processing software, and multiple options for in-building data distribution into a single family of digital subscriber line solutions for routers and voice-over-DSL gateways. This trio of two-chip solutions "takes everything TI has learned about voice-over-DSL," said Terry Reilly, director of business development for TI (stock: TXN). That includes the AX5 ADSL physical-layer (PHY) device TI released last year, Telogy's software, and "the same broadband comms processor architecture" used in TI's voice-over-Internet Protocol cable modem offerings. The result, according to Reilly, is a complete solution that gives customers in multiple segments a fast time-to-market. "And with our level of wireless support, no new wires are needed for the home or small office," he added. Intrinsic to the TI design is the use of an interprocessor-communications link that routes voice packets directly from the on-board C54x digital signal processor to the asynchronous transfer mode segmentation-and-reassembly processor. "This practically eliminates latency to ensure toll-quality voice," said Reilly. The chip set comes in three versions: the AR5D00, the AR5V10, and the AR5V20. All use the AX5 ADSL PHY. Leveraging a common platform, the devices combine high-throughput routing and bridging functionality with interfaces to support all home and office networking standards, such as IEEE 802.11b, Bluetooth, Ethernet, IEEE 1394, USB, power line networking, and Home Phone Networking Alliance. "Meeting all these networking standards allows efficient DSL distribution throughout the home, without having to add new wire," said Reilly. The AR5D00 targets home, Soho, and small-to-medium-enterprise routers. The AR5V10 takes aim at IADs, residential gateways, and Soho gateways to deliver customers up to four packetized voice lines, along with high-throughput data, at what TI says is a lower cost than competing solutions. Finally, the AR5V20 allows IADs and small-to-medium-enterprise gateways to support up to eight packetized voice channels and high-speed data services, decreasing equipment size, power, and operational expenses. All three chip sets leverage either Linux turnkey communications processor software or aVxWorks board support package—both developed by TI. The Linux option includes a complete TCP/IP network stack with advanced network-management features. In addition, the V10 and V20 come with integrated Telogy software. The DSL communications processors at the core of the chip sets feature a USB function controller, two 10/100 Ethernet media-access controllers with media-independent interfaces, and hardware acceleration for virtual private network security. An on-chip PCI interface allows manufacturers to customize the home networking configuration for their end products. At the core of the processors are either one or two C54x DSPs and a 125-MHz MIPS Technologies 4Kc (Jade) microprocessor. Memory comprises 4 kbytes of RAM and 4 kbytes of ROM. All three chip set solutions are sampling today, with volume production planned for the second quarter.
