Broadband Access – Client Side DSL Solutions Integrated VDSL2 CPE Gateway Chipsets CX96xxx - VDSL2 Chipset Family Conexant’s portfolio includes a comprehensive suite of semiconductor solutions for broadband communications and the digital home. The CX96xxx chipset family enables next-generation, wireless VDSL2 gateways, VDSL2 VoIP Integrated Access Devices (IADs), and VDSL2 bridges. This chipset includes a highly integrated Analog Front End (AFE) and a single chip ARM™ based Network Processor (NP), a flexible xDSL DSP core and a field-proven Voice DSP engine. Key features include: • Integrated high performance ARM™ network processor core with routing and switching packet accelerator engine that enables up to one gigabit data throughput • Dedicated Voice Digital Signal Processor (DSP) which frees up processing power for other applications while supporting two complete VoIP channels • Flexible xDSL DSP core architecture available in 30MHz, 17MHz bandwidth and 2-pair bonded configurations enabling cost-optimized products for Fiber-To-The-Building (FTTB), Fiber-To-The-Node (FTTN), and CO deployments, respectively • Fully compatible with legacy ADSL/2/2plus applications enabling the world’s most interoperable ADSL/2/2plus fallback capabilities CX96xxx devices include a wide variety of interfaces that support complementary home networking technologies to provide a complete system solution for xDSL gateways. The CX96xxx SoCs seamlessly integrate with Conexant’s SmartDAA and Subscriber Line Interface Cards (SLIC)/codec chipsets, providing manufacturers a single-source solution for low-cost turnkey triple play applications. Interfaces such as PCI and GMII are also supported to enable emerging home distribution technologies such as Multimedia over Coax Alliance (MoCA®), HomePNA™ specification 3.0 and HomePlug® A/V.
