The AR8031-AL1A is part of the Arctic family of PHYs – which includes the AR8030, AR8033, and AR8035. The AR8031-AL1A is Atheros’ 4th generation, single port, 10/100/1000 Mbps Ethernet PHY. It supports both RGMII and SGMII interfaces to the MAC. The AR8031-AL1A provides a low-power, low BOM (bill-of-materials) cost solution for a wide range of applications, including enterprise, carrier and home networks, including optical modules and media converters. The AR8031-AL1A supports both Sync-E and IEEE1588-V2 timing protcols. 

The AR8031-AL1A device incorporates a 1.25 GHz SERDES which can be connected directly to fiber-optic transceivers for 1000 Base-X/100 Base-FX mode. The AR8031-AL1A integrates Atheros ETHOS-Designed Green Ethernet (EDGE) power saving technologies to automatically save significant power in all operating and idle modes. 

The AR8031-AL1A also supports IEEE 802.3az EEE standard (Energy Efficient Ethernet) with proprietary SmartEEE technology to improve energy efficiency in systems using legacy MAC devices without 802.3az support – enabling customers to fully realize the energy benefits of the new standard by just replacing the PHY devices in their designs.
