With a goal of providing the flexibility to design residential gateways that address multiple networking options, features, enhanced voice and video services, TI announced five xDSL solutions for use across all ADSL and VDSL2 standards.
According to a number of analyst reports, there are 226 million broadband subscribers currently and another 170 million will be added by 2010. The UR8 five chipsets target a number of applications that fit diverse markets worldwide. Within the family, two chipsets support both VDSL2 and ADSL2+ and three support only ADSL2+. The company expects that by 2010, VDSL2 will approach 30 million shipments, and in the same timeframe, ADSL2+ will still be at approximately at 110 million as operators continue to leverage their existing infrastructure while they grow the bandwidth they are able to deliver to the home.
"UR8 is really a multimedia gateway processor addressing the needs of service providers to offer services that require additional bandwidth such as VoIP and IPTV," said Tina Rogers, product line manager at TI's Residential Gateway Business Unit. "What is required is a processor that possesses the performance and an architecture in place to support it."
What makes UR8 unique is the integration of the voice DSP into the UR8 to address the rapid adoption of voice over IP. In addition, to support home networking solutions, UR8 has the interfaces to support MoCA or HPNA, or HomePlug, or WLAN. The UR8 architecture is a gateway processor, a programmable DSL PHY, a high-performance DSP-based voice sub-system and a rich set of local area network (LAN) interfaces. Multiple processors enable the intelligent management of broadband distribution for enhanced throughput and performance. A well-defined application program interface (API) reduces time to market by allowing hardware and software reuse across all DSL platforms.
The UR8 architecture leverages a dedicated DSP to enable exceptional voice capabilities and delivers on TI's vision of Fixed Mobile Convergence (FMC) throughout the home with support for up to four channels of wireline or wireless voice. Its high-performance programmable voice subsystem allows manufacturers to leverage TI's extensive voice codec library and Telogy Software for VoIP, including wideband codecs, wireline and wireless codecs, and advanced features such as fax and modem relay, packet-loss minimization and noise-reducing algorithms.
TI's strong position in mobile devices and voice codecs combine to support dual mode phones--using one phone both when out in the GSM network that immediately changes over to the network in the home. By providing wireless codecs in the gateway itself, the transcoding between the VoIP codec and the wireless codec is eliminated--which will enhance reception quality.
The five new xDSL solutions based on the UR8 RG family are currently sampling.
