Two system-on-chip (SoC) ICs from Conexant Systems Inc. target optical network units (ONUs) that are used on the client-side of fiber-to-the-premises (FTTP) networks. The chips are the first family of SoCs for gigabit and gigabit Ethernet passive optical network (GPON/GE-PON) residential gateway applications, according to the company.
The CX95202 Xenon-IIIG GPON and the CX95203 Xenon-IIIE GE-PON are high-performance devices with a processing capacity of more than 10 Gbits/s. To ensure interoperability, the CX95202 and the CX95203 comply with the ITU G.984 and IEEE 802.3ah PON specifications, respectively. The Xenon-IIIE also complies with China Telecom’s EPON specification. In addition, Conexant successfully conducted extensive tests with leading optical line terminal end-product manufacturers to ensure interoperability on both sides of the connection.
The chips deliver full line-rate performance (2.4 Gbits/s downstream and 1.25 Gbits/s upstream) with complete physical layer encryption, security, bridging, and routing to enable quality of service (QoS) in IP video applications. They offer 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, enable superior QoS, robust security, and complete management of a customer-premises device from the central office. The devices incorporate interfaces for key home networking technologies, including Multimedia over Coax Alliance, HomePNA, HomePlug A/V, and gigabit Ethernet in order to maximize design and application flexibility. The devices come in an 824-pin plastic ball-grid array.
AVAILABILITYThe CX95202 and CS95203 are currently sampling, with volume production scheduled for July. PRICING
The devices cost $29.50 each in quantities of 10,000. FOR MORE INFORMATION
