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.
