DOCSIS 3.0-based high-speed cable modem SoC from ST

ST’s DOCSIS 3.0 modem is capable of bonding sixteen downlink channels and four uplink channels to obtain data speeds of 800Mbps downstream and 108Mbps upstream. These faster modems permit multiple users to experience high-quality full-HD multimedia and interactive Internet services at the same time through the home network. ST’s expertise in this technology covers high wireline data rates.

ST’s DOCSIS 3.0-based cable modem technology is associated with a dual-core ARM Cortex-A9 processor and has applications in routing, switching, telephony, security and media-server functions. With additional multimedia support and security algorithms for pay-TV and Internet-based services, it will be at the heart of a range of ST ICs for applications such as cable set-top boxes, headed/headless gateways, and cable modems.

“DOCSIS 3.0 specification defines the functionality and performance that cable operators need to innovate and enhance services going forwards,” said Laurent Remont, ST’s Digital Convergence Group Vice President and Unified Platform Division General Manager. “Our DOCSIS 3.0-based technology outperforms all others currently available, and will empower ST customers to create advanced products capable of delivering high-quality content and new services such as home automation, home security and e-Health.”

DOCSIS 3.0 Technology:
The Data Over Cable Service Interface Specifications (DOCSIS) cable modem is used by cable service providers and equipment suppliers in major territories worldwide. Widespread adoption of DOCSIS, including EuroDOCSIS throughout Europe, has enabled cable TV operators to become full-service video, voice, and data telecommunications providers.

The latest version, DOCSIS 3.0, supports Internet Protocol TV (IPTV) permitting services such as on-demand content and streaming video, and also supports the next-generation Internet Protocol (IPv6).

DOCSIS 3.0 introduces channel bonding for cable modems which is a flexible technique enabling high-performance devices offering data speeds over 100Mbps. This is a key enabler for delivering rich multimedia services and fast Internet access to multiple home users, simultaneously.

IMS predicts that shipments of DOCSIS 3.0 customer premises equipment to reach 49 million units by 2015.
