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.
