Conexant's broadband communications portfolio includes a comprehensive
suite of semiconductor solutions that enable the digital home and information
network. The Conexant CX86111/3 Network Processor supports complete
networking system solutions for a wide variety of applications in the
residential, commercial, SOHO (small office/home office), and ROBO
(remote office/branch office) environments. Based on an ARM926EJ-S
processor, the CX86111/3 operates at 200-300 MHz,
and
is powerful enough
for the most intensive applications, yet sufficiently flexible to enable designs
that can be leveraged into many different products. Also included is an
integrated memory management unit (MMU) that supports major operating
systems such as Linux, VxWorks and WindowsCE.Net.
In a broadband gateway application, the CX86111/3 Network Processor
can provide Internet access sharing for multiple PCs, while supporting
Ethernet, HomePNA, HomePlug, IEEE 802.11 a/b/g, USB, and other
LAN-side networking and connectivity platforms. Two Ethernet Media
Access Controllers (EMACs) are integrated into the chip providing a
cost-effective solution for any gateway application.
For WAN access, the CX86111/3 Network Processor supports Ethernet
connectivity, as well as xDSL. It is the ideal platform for a configurable
broadband gateway design that can accommodate many diverse WAN/LAN
topologies. The CX86113 has advanced serial and VoIP (Voice over Internet
Protocol) capabilities. It can support up to four lines with G.7xx protocols
running on Conexant voice coprocessors. Both a VoIP phone and a VoIP
gateway can be easily designed using the CX86113.
The CX86111/3 supports high-speed secure virtual private network (VPN)
implementations, with a triple data encryption standard (3DES) designated
hardware engine that accelerates IP security protocol (IPSEC) implementations
performance. CX86111/3 is a highly flexible solution due to its support for
various bus technologies.
The CX86111/3 is based on the Advanced Microcontroller Bus Architecture
(AMBA 2.0) with two internal busses--the Multi-layer Advanced Host Bus
(AHB) and the Advanced Peripheral Bus (APB). The Multi-layer AHB is a
high-performance bus that connects multiple bus masters and supports
internal interfaces with an ARM926 processor, on-chip memory, external
memory controller, DMA controller, and USB Host. The APB connects
peripheral interface blocks to the AHB.
Conexant's home networking products include network processors and
LAN solutions for residential gateway architectures supporting bridging,
routing, security, and wireless functionality. Our home network processor
products service the entire spectrum of broadband access applications
from basic data connectivity to advanced, high speed, and secure voice
and data networks.
