DSP-based cable modem chipsets support DOCSIS 3.0

Dallas, Tex.—Texas Instruments Inc. has introduced the Puma 5 family of DOCSIS 3.0-based (Data Over Cable Service Interface Specification) cable modem chipsets to support CableLabs DOCSIS 3.0 testing in Certification Wave 56.

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. DOCSIS 3.0 features, such as channel bonding, enable ultra high downstream bandwidth rates of at least 160-Mbits/s in the residential data and voice services configuration and 320-Mbits/s 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 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 four upstream and four downstream channels (4×4) and is extendable to eight downstream channels and four upstream channels (8×4) 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.

The latest Puma family leverages TI's 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.

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