Microchip, Ethernet Transceiver, 3.6 V 100 Mbps, 32-Pin QFN

The Microchip low power physical layer PHY transceiver with variable I/O voltage is compliant with the IEEE 802.3-2005 standards. 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 10 Mbps (10BASE-T) and 100 Mbps (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.
