The AR8031 is part of the Arctic family of devices — which includes the AR8031, AR8033, and AR8035. The AR8031 is Atheros' 4^th generation, single port, 10/100/1000 Mbps, Trispeed 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 comprehensive applications including enterprise, carrier and home networks such as CPE, home gateway, enterprise switch, carrier switch/router, mobile base station and base station controller, optical module and media converter, industry automation and measurement. The AR8031 integrates Atheros Green ETHOS^® power saving technologies and significantly saves power not only during the work time, but also overtime. The AR8031 also supports IEEE 802.3az EEE standard (Energy Efficient Ethernet) and Atheros proprietary SmartEEE. The AR8031 requires only a single, 3.3V power supply. The AR8031 supports both 1588v2 and synchronous Ethernet to offer a complete time synchronization solution to meet the next generation network requirements. The AR8031 can attain an additional 25% power savings when a cable length is detected that is <30M vs. standard power consumption for a 100M Cat5 cable. AR8031 supports both crystal and external clock input as reference.

This article provides you with a basic overview of the AR8031 Ethernet Transceiver, including its pin descriptions, features and specifications, etc., to help you quickly understand what AR8031 is.

Billions, maybe trillions of times a day we often do what many thought was impossible. That's how often people around the world touch something made better by Qualcomm. It could be the smartphone in your pocket, the tablet on your coffee table, that wireless modem in your briefcase, it could even be that navigation system in your car or that action camera strapped to your chest. Who is Qualcomm, and what do they do? They are engineers, scientists, and business strategists. They are from many different countries and speak many different languages. They come from diverse cultures and have unique perspectives. Together, they focus on a single goal—invent mobile technology breakthroughs. As the world's industries evolve, so do the connections enabled through our wireless and computing solutions. By helping homes, cars, cities, education, wearables, and healthcare share more interactions and data across a variety of networks, we're weaving the fabric of the Internet of Things so that entire industries can redefine what's possible.
