The number of high-performance network applications demanding low power and design flexibility for Ethernet connectivity are growing rapidly. Applications that formerly required only single-port Ethernet connections now require access to multiple functions or even redundant (fault-tolerant) links.
Cable modems, xDSL modems, IP telephones and telecom backplanes are just a few of the applications demanding dual Ethernet connections. The Intel EGLXT973EA3 is a dual-port 10/100Mbps Ethernet PHY transceiver providing a low-power, feature-rich solution for Ethernet networking.
