The AR8031-AL1A from Qualcomm (formerly Atheros) is a single-port 10/100/1000Mbps Ethernet PHY transceiver in a 48-pin QFN (6x6mm) package. It supports both RGMII and SGMII MAC interfaces, integrates a 1.25GHz SerDes for fiber connectivity, IEEE 802.3az EEE with SmartEEE, IEEE 1588v2, synchronous Ethernet, and Wake-on-LAN, all from a single 3.3V supply.
