Product Details
The LXT971A is an IEEE compliant Fast Ethernet PHY Transceiver that directly supports both 100BASE-TX and 10BASE-T applications. It provides a Media Independent Interface (MII) for easy attachment to 10/100 Media Access Controllers (MACs). The LXT971A also provides a Low Voltage PECL (LVPECL) interface for use with 100BASE-FX fiber networks. Product Features ■ 3.3V Operation. ■ Low power consumption (300 mW typical). ■ Low-power “Sleep” mode. ■ 10BASE-T and 100BASE-TX using a single RJ-45 connection. ■ Supports auto-negotiation and parallel detection. ■ MII interface with extended register capability. ■ Robust baseline wander correction performance. ■ 100BASE-FX fiber-optic capable. ■ Standard CSMA/CD or full-duplex operation. ■ Supports JTAG boundary scan. ■ Configurable via MDIO serial port or hardware control pins. ■ Integrated, programmable LED drivers. ■ 64-ball Plastic Ball Grid Array (PBGA). — LXT971ABC - Commercial (0° to 70°C ambient). —LXT971ABE - Extended (-40° to 85°C ambient). ■ 64-pin Low-profile Quad Flat Package (LQFP). — LXT971ALC - Commercial (0° to 70°C ambient). — LXT971ALE - Extended (-40° to 85°C ambient). Applications ■ Combination 10BASE-T/100BASE-TX or 100BASE-FX Network Interface Cards (NICs) ■ 10/100 PCMCIA Cards ■ Cable Modems and Set-Top Boxes |
