MAY 7, 2007 -- Conexant Systems Inc. (search for Conexant) says it has delivered the world's first family of SoCs for GPON and GE-PON residential gateway applications.
The CX95202 "Xenon-IIIG" GPON and the CX95203 "Xenon-IIIE" GE-PON devices are targeted at optical network units (ONUs) that are used on the client-side of FTTP networks. The devices have a processing capacity of more than 10 Gbits/sec, Conexant says.
"Operators worldwide are planning to use PON technology for next-generation network upgrades to improve their ability to deliver bandwidth-intensive services such as video-on-demand and IPTV," said Akram Atallah, senior vice president and general manager of Conexant's Broadband Access business. "With the launch of our new 'world's first single-chip' PON residential gateway solutions, we now offer our customers a comprehensive portfolio of industry-leading solutions that deliver the performance required for both advanced DSL and next-generation fiber-optic networks."
"Carriers are moving as quickly as they can to establish robust networks that have the speed and capacity required for triple-play service deployments," said Aileen Arcilla, senior research analyst for market research firm IDC. "PON is becoming a viable broadband access technology to be implemented in residential gateways, which are critical to driving mass subscriber growth."
Conexant says the Xenon-III product family provides manufacturers with a flexible option that enables them to address multiple applications in a cost-effective and efficient manner. For example, the Xenon-IIIG and Xenon-IIIE are pin- and software-compatible, enabling product developers to address GPON and GE-PON deployments with the same hardware and software platform. The devices can also be used with Conexant's VDSL2 CO and CPE devices to provide carriers with a cost-effective, end-to-end system approach for fiber-to-the-node applications.
To ensure interoperability, the Xenon-IIIG and Xenon-IIIE SoCs are based on ITU G.984 and IEEE 802.3ah PON industry specifications, respectively. Xenon-IIIE also complies with China Telecom's EPON specification. In addition, Conexant successfully conducted extensive tests with "leading optical line terminal (OLT) end-product manufacturers" to further ensure interoperability on both sides of the connection.
The Xenon-IIIG and Xenon-IIIE include several features that improve performance and lower system costs including:
- Full line-rate performance at 2.4 Gbits/sec downstream and 1.25 Gbits/sec upstream with complete physical layer encryption, security, bridging, and routing required to enable quality of service (QoS) in IP video applications.
- Integrated functionality for four concurrent voice-over-IP channels, three-way calling, and a T.38 fax demodulator.
- Enhanced routing capabilities combined with deep classification and filtering support to enable superior QoS, robust security, and complete management of a customer premises device from the central office.
- Interfaces for home networking technologies including Multimedia over Coax Alliance (MoCA), HomePNA, HomePlug A/V, and Gigabit Ethernet.
The Xenon-III product family comes bundled with an open-source-based Linux board support package, Conexant's Integrated-System-On-Silicon (ISOS) software protocol stacks, and support for customers' own software stacks. This same software can be used in the development of broadband access gateway products for ADSL, VDSL, GPON, and GE-PON, allowing manufacturers to reduce engineering design cycles and maximize engineering resources.
The CX95202 Xenon-IIIG and CX95203 Xenon-IIIE SoCs are packaged in an 824-pin plastic ball grid array (PBGA) and priced at $29.50 each in quantities of 10,000. They are currently sampling, with volume production slated for July 2007.
