The AR8031 is part of the Arctic family of PHYs – which includes the AR8030, AR8033, and AR8031.
This is Qualcomm  4th generation, single port, 10/100/1000 Mbps Ethernet PHY. It supports both RGMII and SGMII interfaces to the MAC. The AR8031 provides a low-power, low BOM (bill-of-materials) cost solution for a wide range of applications, including enterprise, carrier and home networks, SFP modules and media converters. The device supports both Sync-E and IEEE1588-V2 timing protcols.
