Overview
Data Sheet July 2010 AR8032 Integrated 10/100 Fast Ethernet Transceiver General Description The Atheros AR8032 Fast Ethernet transceiver is a highly integrated physical layer device that transmits and receives high-speed data over standard category 5 (CAT 5) unshielded twisted pair cable.
The AR8032 is compliant with 100 BASE-TX and 10 BASE-T IEEE 802.
3 standards.
The AR8032 device uses advanced mixed-signal processing technology and integrates functions such as adaptive equalization, and timing recovery to deliver substantial power savings and operation in noisy environments.
The AR8032 device supports the Media Independent Interface (MII) and Reduced Media Independent Interface (RMII) for direct connection to a Fast Ethernet-capable MAC.
The AR8032 supports the Atheros Cable Diagnostic Test (CDT) feature, which uses Time Domain Reflectometry (TDR) technology to quickly and remotely identify potential cable malfunctions without deploying field support personnel or bringing down the network.
The AR8032 solution detects and reports issues such as PHY malfunctions, bad/marginal cable or patch cord segments or connectors, thus significantly reducing installation time, cable debug efforts, and overall network support cost.
Manufactured in a standard CMOS process, the AR8032 is packaged in a 32-pin QFN, featuring a small body size of 5 x 5mm.
