Texas Instruments (TI) announced a milestone in the effort to bring DOCSIS 3.0-based (Data Over Cable Service Interface Specification) solutions to market. TI’s Puma 5 family of DOCSIS 3.0-based cable modem chipsets are supporting CableLabs DOCSIS 3.0 testing in Certification Wave 56.
TI’s Puma 5 family has been developed to support DOCSIS 3.0 enhanced performance and features, including channel bonding, which enable 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 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.
TI said its flexible architecture supports 4 upstream and 4 downstream channels (4×4) and is extendable to 8 downstream channels and 4 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 4 channel operation enabling a very cost effective implementation.
