LAN8740A-EN

The LAN8740A-EN is a low-power 10Base-T/100Base-TX Physical-layer (PHY) Transceiver with variable I/O voltage that is compliant with the IEEE 802.3, 802.3u and 802.3az (energy efficient Ethernet) standards. Energy Efficient Ethernet (EEE) support results in significant power savings during low link utilizations. It supports communication with an Ethernet MAC via a standard MII (IEEE 802.3u)/RMII interface. It contains a full-duplex 10-BASE-T/100BASE-TX transceiver and supports 10Mbps (10Base-T) and 100Mbps (100Base-TX) operation. It implements auto-negotiation to automatically determine the best possible speed and duplex mode of operation. HP Auto-MDIX support allows the use of direct connect or cross-over LAN cables. Integrated Wake on LAN (WoL) support provides a mechanism to trigger an interrupt upon reception of a perfect DA, broadcast, magic packet, or wakeup frame. It supports both IEEE 802.3-2005 compliant and vendor-specific register functions.
