Conexant’s broadband communications portfolio includes a comprehensive
suite of semiconductor solutions that enable the digital home and information
network. The Conexant CX8620x Network Processor supports complete
networking system solutions for a wide variety of mainstream applications in
the residential and SOHO environments. Based on a 180 MHz ARM926, this
network processor is a single-chip solution with an integrated switch that
supports five 10/100 Mbps Ethernet ports with auto MDIX capabilities.
In a broadband gateway application, the CX8620x network processor can
provide Internet access sharing capability for multiple PCs, while supporting
Ethernet, 802.11 through a PCI interface and any USB2.0 device including
hard disk drives and printers. For WAN access, the unit supports Ethernet
connectivity interoperable with any broadband modem. It is the ideal platform
for a configurable broadband gateway design that needs to accommodate
many diverse WAN/LAN topologies.
The device complies with IEEE 802.3 specification and includes five
embedded DSP-based 10Base-T/100Base-TX transceivers. An auto
negotiation function determines the selection of either the 10Base-T or
100Base-Tx mode. Typical applications would be a wireless home gateway
including an Ethernet WAN port to connect to a broadband modem, four
Ethernet LAN ports, an 802.11 a/b/g access point connecting any Wi-Fi
compatible device and a home storage device connected through the
USB2.0 host.
