AR8033 Integrated 10/100/1000 Mbps Ethernet Transceiver

The AR8033 Ethernet transceiver is a single port, 10/100/1000 Mbps tri-speed Ethernet PHY. TheAR8033 Ethernet transceiver supports both RGMII and SGMII to the MAC. The AR8033Ethernet transceiver belongs to the Arctic™ PHY family which provides a low power, low BOMcost solution for comprehensive applications including enterprise, carrier and home networks suchas CPE, home gateway, enterprise switch, carrier switch/router, mobile base station and basestation controller, optical module and media converter, industrial automation and measurement.The AR8033 Ethernet transceiver integrates Green ETHOS® power saving technologies whichsignificantly save power in both active operation and idle condition. Green ETHOS power savingschemes include ultra-low power in cable unplugged mode or port power down mode, as well asautomatically optimized power saving based on cable length. The AR8033 Ethernet transceiversupports standard IEEE 802.3az Energy Efficient Ethernet (EEE) and Qualcomm Atherosproprietary SmartEEE™. SmartEEE allows legacy MAC and SoC devices without IEEE 802.3azsupport to cowork with AR8033 to provide full IEEE 802.3az support. Furthermore, the AR8033Ethernet transceiver supports Wake-on-LAN (WoL) feature to manage and regulate total systempower requirements.

The AR8033 Ethernet transceiver embeds Cable Diagnostics Test (CDT) technology formeasuring cable length, detecting the cable status, and identifying remote and local PHYmalfunctions, bad or marginal patch cord segments or connectors.The AR8033 Ethernet transceiver requires only a single 3.3 V power supply. Embedded regulatorsare used to generate other required voltages. The AR8033 Ethernet transceiver integrates thetermination circuitry at the line side.The AR8033 Ethernet transceiver incorporates a 1.25 Gbps SerDes. This interface can beconnected directly to a fiber-optic transceiver for 1000BASE-X/100BASE-FX mode or used asSGMII with MAC.The AR8033 Ethernet transceiver supports Synchronous Ethernet by offering recovered clockoutput from data on the network-line side.The AR8033 Ethernet transceiver supports IEEE 802.3az standard. The key features include:

 10BASE-Te PHY uses reduced transmit amplitude.

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