Texas Instruments Inc. (TI) has introduced the Puma 5 family of DOCSIS 3.0-based cable modem chipsets to support CableLabs DOCSIS 3.0 testing in Certification Wave 56. This milestone will help drive the next wave of cable modem innovation and services, the company said.

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, such as channel bonding, which enable ultrahigh downstream bandwidth rates of at least 160Mbps in the residential data and voice services configuration and 320Mbps in video and business services configuration. In addition TI's Puma 5 also supports greater QoS with IPv6 and security with Advanced Encryption Standard.

The Puma 5 architecture includes an advanced multimedia processor and routing accelerator along with a DSP-based voice subsystem and a rich set of LAN interfaces. The routing accelerator provides line rate bridging and routing capabilities and enables QoS guarantees for voice traffic even in the presence of very high data packet throughput. The flexible architecture supports four upstream and four downstream channels (4 x 4) and is extendable to eight downstream channels and four upstream channels (8 x 4) 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 four-channel operation, enabling a 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 includes the TNETC4800, TNETC4810 and TNETC4830. The TNETC4800 supports full functionality EMTA applications and includes a battery backup subsystem. The TNETC4810 is optimized for EMTA applications without battery backup. 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 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.

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