Ethernet :: AR8030
Technology Overview
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.
AR8030 Product Overview
The AR8030 is part of the Arctic family of PHYs – which also includes the AR8031, AR8033, and the AR8035. It is Atheros' 4th generation, single port 10/100 Mbps Ethernet PHY. It supports an RMII interface to the MAC with wide RGMII I/O voltage support from 1.5V to 3.3V.
The AR8030 integrates Atheros latest ETHOS-Designed Green Ethernet (EDGE™) power-saving technologies and significantly saves power in all operating and idle modes.
Atheros EDGE power-savings include ultra-low-power in cable-unplugged mode or port power-down mode, and automatic optimized power-saving based on cable length. The AR8035 supports the latest IEEE 802.3az-2010, Energy Efficient Ethernet (EEE) standard 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 AR8030 supports Wake-on-LAN (WoL), embeds CDT (Cable Diagnostics Test) technology on-chip and integrates a voltage regulator on chip, enabling it to operate from a single 3.3V supply. It reduces the termination R/C circuitry on both the MAC interface (RMII) and line side. The AR8030 provides a low-power, low BOM (bill-of-materials) solution for a wide range of applications – including consumer, enterprise, carrier and home network products such as set-top box, connected TV, printer, game console, xDSL/ xPON CPE, telecom embedded system, voice and video phone, digital media player/eReader devices, and LAN-on-motherboard.
The AR8030 supports co-layout with the AR8035 Gigabit Ethernet PHY.
