CX84200
Single-Chip Solution with Integrated
Five-Port Ethernet Switch
Conexant鈥檚 broadband communications portfolio includes a comprehensive
suite of semiconductor solutions that enable the digital home and
information network. The Conexant CX84200 Network Processor supports
complete networking system solutions for a wide variety of mainstream
applications in the residential and SOHO environments. Based on a 75 MHz
ARM7TDMI, this Network Processor is a single-chip solution with an
integrated switch that supports five 10/100 Mbps Ethernet ports.
In a Broadband Gateway application, the CX84200 Network Processor can
provide Internet access sharing capability for multiple PCs, while supporting
Ethernet, HomePNA (Phoneline), HomePlug (Powerline), IEEE 802.11 and other
LAN-side networking platforms. 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, and an
802.11b access connecting to any Wi-Fi compatible device.
