TI Offers Simple Voice Over Broadband Solutions

Compiled ByTraci Purdum Texas Instruments Inc. (TI) is offering manufacturers and service providers a plain old telephone service (POTS) solution for voice over broadband. According to the Dallas-based company, the solution will quickly deploy enhanced voice capabilities on existing broadband platforms in a cost-effective manner. TI's TP2450 quad channel codec, the first in a family of programmable voice codecs solutions that convert an analog signal to a digital signal for transmission, directly interfaces with a dual ringing Subscriber Line Interface Circuit (ISL5587) from Irvine, Calif.-based Intersil Corp., a wireless networking and power management provider. The solution can be used in network interface devices, SME gateways or CPE devices such as home routers and gateways, DSL and cable modems, and multimedia terminal adapters. It also provides a migration path to next-generation voice services. "The voice over broadband customer premise market is expected to grow at a 74% annual rate to over 27 million ports shipped by 2006," says Will Strauss of market researcher Forward Concepts, Tempe, Ariz. "With flexible, low-power solutions such as TI's TP2450, equipment vendors can more quickly get cost-effective products to this growing market." Support for the TP2450 and ISL5587 combined solution includes analog reference designs, joint TI and Intersil evaluation modules, individualized customer support and Telogy Software products. The TP2450 and ISL5587 are currently sampling and volume production is expected in early 2003. Prices will range from $7 to $8 for the quad channel codec and $5 to $6 for the dual channel SLIC, depending on volume.
