TI Debuts VoCable Chipset and Wideband DOCSIS Design

Texas Instruments announced the availability of its advanced voice-over-cable (VoCable) chipset and new Wideband DOCSIS reference design.


TI's DSP-based TNETC47xx (Puma-4) VoCable chipset incorporates advancements to process cellular codecs, setting the stage for fixed mobile convergence with phones that operate on cellular or VoIP connections, depending on the user's choice and proximity to either network. The company said its low bit-rate codecs for conferencing channels use half the bandwidth currently consumed for multi-user calls, saving bandwidth for other applications while maintaining high data rates. The TNETC47xx also has advanced fax capabilities. TI's TNETC47xx chipset will sample in the fourth quarter of 2005.


TI also announced a Wideband DOCSIS reference design that lets equipment manufacturers and service providers evaluate system architectures today. TI expects to deliver its first Wideband DOCSIS reference designs in Q4.


"Wideband DOCSIS channel bonding will enable cable operators to surpass current DSL and FTTX data rates by delivering more than 100 Mbps to an individual subscriber" said Bruce McClelland, VP/GM ARRIS Broadband CPE Products.


Wideband DOCSIS technology will incorporate multiple down and up streams in a single modem, providing higher broadband speeds and greater bandwidth to both business and consumer subscribers. As the standard evolves to include voice, the increased bandwidth and enhanced performance of DOCSIS 3.0 modems will support VoIP conversations and video downloading without impacting the stream of information delivered to and from the home or office.
