CX86201

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. CX8620x is the ideal platform for a configurable broadband gateway design that needs to accommodate many diverse WAN/LAN topologies.

CX8620x 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.
