Ethernet :: AR8031
Atheros ETHOS® technologies provide customers with industry-leading low-power and solution size to enable Fast or Gigabit Ethernet connectivity in networking equipment, consumer electronics and computing platforms. Our PHY, controller and switch solutions support the IEEE 802.3az standard for Energy Efficient Ethernet, to extend battery- charges on computing platforms and deliver power-efficiencies in networking equipment. Atheros also enables incremental power-saving techniques to offer our customers the very lowest power Ethernet in the industry today. The unmatched efficiency and advanced carrier-class features of Atheros ETHOS solutions give customers a competitive edge when designing products for energy-conscious consumers and businesses.
AR8031 Product Overview
The AR8031 is part of the Arctic family of PHYs – which includes the AR8030, AR8033, and AR8035. The AR8031 is Atheros’ 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, including optical 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 Atheros 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.
