Video: Texas Instruments Delivers on the Promise of DOCSIS® 3.0 with its Puma 5 Family

DALLAS, Oct. 2 / / - Texas Instruments (TI) Incorporated (NYSE:TXN) today announced that the company is delivering on its promise to introduce the Puma 5 family of DOCSIS(R) 3.0-based (Data Over Cable Service Interface Specification) cable modem chipsets to support CableLabs(R) DOCSIS 3.0 testing in Certification Wave 56. This milestone will help drive the next wave of cable modem innovation and services.

Optimized for triple play and next generation IP services, TI's Puma 5 family has been developed to support DOCSIS 3.0 enhanced performance and features. New DOCSIS 3.0 features, such as channel bonding, enable ultra high downstream bandwidth rates of at least 160 Mbps in the residential data and voice services configuration and 320 Mbps in video and business services configuration. In addition TI's Puma 5 also supports greater quality of service with IPv6 and security with Advanced Encryption Standard (AES).

The Puma 5 architecture includes an advanced multimedia processor and routing accelerator along with a high-performance DSP-based voice sub-system and a rich set of local area network (LAN) interfaces. The routing accelerator provides line rate bridging and routing capabilities and enables quality of service guarantees for voice traffic even in the presence of very high data packet throughput. The flexible architecture supports 4 upstream and 4 downstream channels (4x4) and is extendable to 8 downstream channels and 4 upstream channels (8x4) to support next generation IP services. In addition, Puma 5 contains a high speed sampling engine that enables a single tuner to be used for 4 channel operation enabling a very cost effective implementation.

"TI is excited to deliver Puma 5 to our customers and to support their efforts in the first DOCSIS 3.0 certification wave," said Ran Senderovitz, Cable Business Manager with TI. "The differentiated products they are creating will help drive next generation Cable services and we are happy be to supporting this endeavor."

The latest Puma family leverages TI's field proven Cable technology, and includes the TNETC4800, TNETC4810 and TNETC4830. The TNETC4800 supports full functionality EMTA applications and includes a battery back up subsystem. The TNETC4810 is optimized for EMTA applications without battery back up. The TNET4830 is optimized for data cable modem applications. The EMTA solutions incorporate a dedicated DSP to enable exceptional voice capabilities and deliver 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(TM) for VoIP.

TI's Puma 5 family of Cable modem chipsets is available today.
