AR8031-AL1A

1. Description

AR8031-AL1A is part of the Arctic series, single port, 10/100/1000 Mbps, Trispeed Ethernet PHY. It also supports RGMII SGMII and MAC interface. AR8031-AL1A provides low power consumption and low BOM (Bill of Materials) Cost Solution Comprehensive applications include Enterprise, carrier and home network, such as CPE, home gateway, enterprise switch, operator Switches/routers, mobile base stations and base stations Station controller, optical module and media Frequency converter, industrial automation and measuring.

AR8031-AL1A integrates Atheros GreenETHOS® Power saving technology Not only save working time, And also work overtime. Atheros Green ETHOS® Energy saving includes ultra-low power consumption Cable unplug mode or port power failure Mode and automatically optimize power saving According to cable length. AR8031-AL1A also Support IEEE 802.3az EEE standard (energy Efficient Ethernet) and Atheros proprietary SmartEEE. SmartEEE allows the use of older MAC/SoC Devices that do not support 802.3az can be used as Complete 802.3az system. In addition, AR8031-AL1A Support Wake on LAN (WoL) function Can help manage and standardize the entire system Power requirements.

AR8031-AL1A embedded CDT (cable diagnostic Test) on-chip technology Customer measures the cable length and inspects Cable status and identify remote and local PHY Fault, bad jumper or narrow edge Segment or connector. Some possibilities Problems that can be detected include opening, Short circuit, cable impedance mismatch, bad Connector, terminal mismatch and damage transformer. AR8031-AL1A only requires a single 3.3V power supply supply. On-chip voltage regulator provides all Other required voltages. It integrates Terminal R/C circuit on two MACs Interface (RGMII / SGMII) and serial Resistance on the line side. The AR8031-AL1A device also integrates 1.25 GHz SerDes. The interface can be connected Optical transceiver directly to 1000 BASE-X / 100 BASE-FX mode or MAC SGMII interface equipment. AR8031-AL1A supports 1588v2 and Synchronous Ethernet provides complete time Meet the next synchronization solution Generate network requirements. Key new The functions supported by the device are: Clock synchronization between slave and clock Master of exchange PTP package. Support IEEE 1588v2 by providing the following: 1588 package analyzer, accurate time stamp And inserted to support one step and Two-step clock mode. Support IEEE 1588v2 and Synchronous Ethernet by providing recovery Clock output of network line data side.

AR8031-AL1A supports IEEE 802.3az Energy Efficient Ethernet (EEE) standard. key The functions supported by the device are: 10 BASE-Te PHY uses reduced emission amplitude. 100 BASE-TX and 1000 BASE-T use low Power Idle (LPI) mode can turn off unused power Analog and digital modules to save power When data traffic is idle.
