description

The TNETE2004 QuadPHY interface device is a single-chip, multi-PHY (four 10BASE-T devices),

high-performance solution for designers of 10BASE-T networking systems. The highly integrated TNETE2004

includesauser-programmableSNIsignalforeachPHY. EachPHYinterfaceonthedeviceprovidesManchester

encoding/decoding of data via unshielded twisted-pair (UTP) balanced cable through simple isolation

transformers requiring no external filtering. Additional TNETE2004 features are smart squelch, jabber

detection, auto-polarity correction, transmission wave shaping, and anti-alias filtering capabilities. Each PHY

interface on the TNETE2004 is individually addressable within the TNETE2004 via the MDIO.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
