Datasheet for Qualcomm Atheros AR8031

Ultra low-power 10/100/1000 RGMII/SGMII Gigabit Ethernet Transceiver

AR8031 Product Overview
The AR8031 is part of the Arctic family of PHYs – which includes the AR8030, AR8033, and AR8031. The AR8031 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 AR8031 supports both Sync-E and IEEE1588-V2 timing protcols. The AR8031 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 integrates Qualcomm ETHOS-Designed Green Ethernet (EDGE) power saving technologies to automatically save significant power in all operating and idle modes. The AR8031 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.
The AR8031 also supports Wake-on-LAN (WoL), embeds CDT (Cable Diagnostics Test) technology on-chip, and requires only a single, 3.3V power supply. On-chip regulators provide the other voltages. It integrates the termination R/C circuitry on both the MAC interfaces (RGMII/SGMII) and the line side.
