CX95202-12Z

Conexant's portfolio includes a comprehensive suite of semiconductor solutions for communications and consumer applications.

Xenon-IIIG (CX95202-12Z) Gigabit Passive Optical Network (GPON) gateway is targeted at the Optical Network Terminals (ONTs) used on the client-side of Fiber-To-The-Premises (FTTP) PON connections. The System-on-Chip (SoC) supports the ITU-T G.984 GPON GEM service, GTC, and GPON PMA functions to implement GPON ONTs. It's the world's first GPON ONT SoC targeting Network Interface Device (NID) as well as residential gateway applications.

A Complete System-on-Chip

Xenon-IIIG is a highly integrated GPON ONT and gateway SoC that includes an integrated Serializer/Deserializer with clock and data recovery (SerDes/ CDR) block to allow manufacturers to reduce the overall system cost of the ONT. In addition, the Xenon-IIIG incorporates the following features: ITU-T G.984 MAC/TC, AES, FEC, Integrated Voice Processing, Layer 3 Routing and Gateway Functions, advanced 802.1p Quality of Service (QoS) management, 802.1D VLAN tagging and bridging, and Layer 2, 3 and 4 based classification. The device also includes a very powerful packet processing engine to enable advanced 802.1p and 802.1Q-based QoS features for flexible data path mapping modes as well as time sensitive applications such as voice and video. Xenon-IIIG allows manufacturers to deliver the most integrated single chip, feature rich residential gateway ONT in the market with all the key residential data networking features.

Coupled with the company's integrated CODEC w/SLIC and USB PHY devices, Xenon-IIIG provides carriers and OEMs with a cost-effective system solution for GPON Fiber-To-The-Home (FTTH) Network Interface Device (NID) and residential gateway applications. Xenon-IIIG also provides carriers and OEMs with a complete system solution for Fiber-To-The-Node (FTTN) applications when combined with Conexant's market leading Accelity VDSL2 products.
