SoC line launches for fiber optic gateways

Newport Beach, Calif.—Conexant Systems Inc. is shipping what it says is the first family of system-on-chips (SoCs) for gigabit and gigabit Ethernet passive optical network (GPON/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 fiber-to-the-premises (FTTP) networks. The high-performance devices have a processing capacity of more than 10-Gbits/s.

PON technology provides operators with additional bandwidth capacity, enabling them to cost-effectively deliver triple-play voice, video, and data services over a fiber optic cable. PON is also used to provide a high-speed “last mile” connection from a central office (CO) to homes and businesses.

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 customer premises equipment (CPE) devices to provide carriers with a cost-effective, end-to-end system solution for fiber-to-the-node (FTTN) 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.

The Xenon-IIIG and Xenon-IIIE feature full line rate performance at 2.4-Gbits/s downstream and 1.25-Gbits/s upstream with complete physical layer encryption, security, bridging and routing required to enable quality of service (QoS) in IP video applications.

They also feature 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.

Interfaces for key home networking technologies include Multimedia over Coax Alliance (MoCA), HomePNA(TM), HomePlug A/V and gigabit Ethernet, to maximize design and application flexibility.

Pricing: $29.50 each in quantities of 10,000.
Availability: Sampling with volume production slated for July 2007.
