Product Descriptions

The AR8033 Ethernet transceiver is a single port, 10/100/1000 Mbps tri-speed Ethernet PHY. The AR8033 Ethernet transceiver supports both RGMII and SGMII to the MAC. The AR8033 Ethernet transceiver belongs to the Arctic™ PHY family which provides a low power, low BOM 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, industrial automation and measurement.

The AR8033 Ethernet transceiver integrates Green ETHOS® power saving technologies which significantly save power in both active operation and idle condition. Green ETHOS power saving schemes include ultra-low power in cable unplugged mode or port power down mode, as well as automatically optimized power saving based on cable length. The AR8033 Ethernet transceiver supports standard IEEE 802.3az Energy Efficient Ethernet (EEE) and Qualcomm Atheros proprietary SmartEEE™. SmartEEE allows legacy MAC and SoC devices without IEEE 802.3az support to cowork with AR8033 to provide full IEEE 802.3az support. Furthermore, the AR8033 Ethernet transceiver supports Wake-on-LAN (WoL) feature to manage and regulate total system power requirements.

The AR8033 Ethernet transceiver embeds Cable Diagnostics Test (CDT) technology for measuring cable length, detecting the cable status, and identifying remote and local PHY malfunctions, bad or marginal patch cord segments or connectors. 

The AR8033 Ethernet transceiver requires only a single 3.3 V power supply. Embedded regulators are used to generate other required voltages. The AR8033 Ethernet transceiver integrates the termination circuitry at the line side.

The AR8033 Ethernet transceiver incorporates a 1.25 Gbps SerDes. This interface can be connected directly to a fiber-optic transceiver for 1000BASE-X/100BASE-FX mode or used as SGMII with MAC.

The AR8033 Ethernet transceiver supports Synchronous Ethernet by offering recovered clock output 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 analog and digital blocks to save power when data traffic is idle.
