Product Description

AR8031-AL1A Integrated Circuit Chip Integrated 10/100/1000 Mbps Ethernet Transceiver

 

 

General Description

 

         The AR8031 is part of the Arctic family of devices — which includes the AR8031, AR8033, and AR8035. The AR8031 is Atheros’ 4th generation, single port, 10/100/1000 Mbps, Tri- speed 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. Atheros Green ETHOS® 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 AR8031 also supports IEEE 802.3az EEE standard (Energy Efficient Ethernet) and Atheros proprietary SmartEEE. SmartEEE allows legacy MAC/SoC devices without 802.3az support to function as a complete 802.3az system. Further, the AR8031 supports Wake-on-LAN (WoL) feature to be able to help manage and regulate total system power requirements.

 

        The AR8031 embeds CDT (Cable Diagnostics Test) technology on-chip which allows customers to measure cable length, detect the cable status, and identify remote and local PHY malfunctions, bad or marginal patch cord segments or connectors. Some of the possible problems that can be detected include opens, shorts, cable impedance mismatch, bad connectors, termination mismatch, and a bad transformer.

 

 

         The AR8031 requires only a single, 3.3V power supply. On-chip regulators provide all the other required voltages. It integrates the termination R/C circuitry on both the MAC interfaces (RGMII/SGMII) and the serial resistors for the line side.

 

        The AR8031 device also incorporates a 1.25 GHz SerDes. This interface can be connected directly to a fiber-optic transceiver for 1000 BASE-X /100 BASE-FX mode or to MAC device for SGMII interface. The AR8031 supports both 1588v2 and synchronous Ethernet to offer a complete time synchronization solution to meet the next generation network requirements. The key new features supported by the device are:

 

Clock synchronization between slave and grandmaster by the exchange of PTP packets. Supports IEEE 1588v2 by offering a 1588 paket parser, accurate time-stamping and insertion to support both one-step and two-step clock modes

 

Supports both IEEE 1588v2 and Synchronous Ethernet by offering recovered clock output from data on the network-line side. The AR8031 supports IEEE 802.3az Energy Efficient Ethernet (EEE) standard. The key features supported by the device are:

 

10 BASE-Te PHY uses reduced transmit amplitude.

 

100 BASE-TX and 1000 BASE-T use Low Power Idle (LPI) mode to turn off unused analog and digital blocks to save power while data traffic is idle.

 

 

Features

 

10/100/1000 BASE-T IEEE 802.3 compliant
