LXT97310

The Cortina Systems® LXT97310/100 Mbps Dual-Port Fast Ethernet PHY Transceiver (LXT973 Transceiver) is an IEEE 802.3 compliant, dual-port, Fast Ethernet PHY transceiver that directly supports both 100BASE-TX and 10BASE-T applications. Each port provides a Media Independent Interface (MII) for easy attachment to 10 Mbps and 100 Mbps Media Access Controllers (MACs). The LXT97310 Transceiver also provides a Low-Voltage Positive Emitter Coupled Logic (LVPECL) interface per port for use with 100BASE-FX fiber networks. The LXT973 Transceiver incorporates the auto MDI/MDIX feature, allowing it to automatically switch twisted-pair inputs and outputs.

The LXT97310 Transceiver is an ideal building block for systems that require two Ethernet ports, such as Internet Protocol (IP) Telephones, Twisted-Pair (TX)-to-Fiber (FX) converter modules, and for telecom applications, such as Telecom Central Office (TCO) and Customer Premise Equipment (CPE) devices.

The LXT97310 Transceiver supports full-duplex operation at both 10 Mbps and 100 Mbps. Its operating modes can be set using auto-negotiation, parallel detection, or manual control.
