Gigabit Passive Optical Network Chips - Xenon-IIIG/E - Conexant

Conexant introduced the the CX95202 Xenon-IIIG GPON (Gigabit Passive Optical Network) and the CX95203 Xenon-IIIE GE-PON (Gigabit Ethernet Passive Optical Network) SoCs (System on Chips). The new devices are targeted at Optical Network Units (ONUs) that are used on the client-side of fiber-to-the-premises (FTTP) networks. Booth chips offer more than 10 gigabits per second (Gb/s) of processing speed.  Passive Optical Network (PON) technology enabling the operators to cost-effectively deliver triple-play voice, video, and data services over a fiber optic cable.

Akram Atallah, Conexant's Broadband Access business said:

Operators worldwide are planning to use Passive Optical Network technology for next-generation network upgrades to improve their ability to deliver bandwidth-intensive services such as video-on-demand and IPTV…

With the launch of our new 'world's first single-chip' Passive Optical Network 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…

The Xenon-III Passive Optical Network chips enable manufacturers to address multiple applications efficiently. For example, the Xenon-IIIG Passive Optical Network and Xenon-IIIE Passive Optical Network 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 customer premises equipment (CPE) devices to provide carriers with a cost-effective, end-to-end system solution for fiber-to-the-node (FTTN) applications.

Key features Xenon-IIIG and Xenon-IIIE Passive Optical Network chips:

• Integrated functionality for four concurrent voice-over-IP channels, three-way calling, and a T.38 fax demodulator to provide a highly integrated, cost-effective voice gateway solution.
• Full line rate performance at 2.4 Gb/s downstream and 1.25 Gb/s upstream with complete physical layer encryption, security, bridging and routing required to enable quality of service (QoS) in IP video applications.
• Interfaces for key home networking technologies including Multimedia over Coax Alliance (MoCA), HomePNA(TM), HomePlug(R) A/V and gigabit Ethernet, to maximize design and application flexibility.
• 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.

The Xenon-III Passive Optical Network chips comes bundled with an open source-based Linux board support package, Conexant's widely deployed 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, G-Passive Optical Network and GE-Passive Optical Network, allowing manufacturers to reduce engineering design cycles and maximize engineering resources.

Xenon-IIIG Passive Optical Network and Xenon-IIIE Passive Optical Network SoCs are based on ITU G.984 and IEEE 802.3ah Passive Optical Network industry specifications. Xenon-IIIE Passive Optical Network also complies with China Telecom's EPON specification

The CX95202 Xenon-IIIG Passive Optical Network and CX95203 Xenon-IIIE Passive Optical Network SoCs are in sampling now. Volume product is scheduled  to be available in July this year
