Data Sheet FEBRUARY 2000 Revision 1.1 LXT971 3.3V Dual-Speed Fast Ethernet Transceiver General Description Features The LXT971 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 LXT971 also provides a pseudo-ECL (PECL) interface for use with 100BASE-FX fiber networks. • 3.3V Operation. The LXT971 supports full-duplex operation at 10 Mbps and 100 Mbps. Its operating condition can be set using auto-negotiation, parallel detection, or manual control. • MII interface with extended register capability. • 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. • Robust baseline wander correction performance. • 100BASE-FX fiber optic capable. The LXT971 is fabricated with an advanced CMOS process and requires only a single 3.3V power supply. • Standard CSMA/CD or full-duplex operation. • Configurable via MDIO serial port or hardware control pins. Applications • Integrated, programmable LED drivers. • Combination 10BASE-T/100BASE-TX or 100BASE-FX Network Interface Cards (NICs) • 64-pin Plastic Ball Grid Array (PBGA). • LXT971BC - Commercial (0° to 70°C ambient). • LXT971BE - Extended (-40° to 85°C ambient). • 64-pin Low-profile Quad Flat Package (LQFP). • LXT971LC - Commercial (0° to 70°C ambient). • LXT971LE - Extended (-40° to 85°C ambient). • 10/100 PCMCIA Cards • Cable Modems and Set-Top Boxes LXT971 Block Diagram RESET Register Set Manchester Encoder TX_CLK Parallel/Serial Converter TX PCS TX_ER Scrambler & Encoder 10 OSP ™ 100 Pulse Shaper TxSLEW<1:0> TP Driver ECL Driver Auto Negotiation + TPFOP + TP / Fiber Out JTAG Collision Detect Clock Generator Media Select OSP ™ Adaptive EQ with Baseline Wander Cancellation + RXDV CRS RX_ER RX PCS R X D <3:0> Carrier Sense Data Valid Error Detect 10 Manchester Decoder 100 Decoder & Descrambler OSP ™ 5 TDIO, TMS, TCK, TRST 100TX + RX_CLK Serial-toParallel Converter TPFON - Register Set L E D / C F G <3:1> COL REFCLK Clock Generator TX_EN T X D <3:0> VCC GND PWRDWN Pwr Supply Management / Mode Select Logic ADDR<4:0> MDIO MDC MDINT MDDIS 100FX + Slicer TP / Fiber In TPFIP TPFIN SD/TP 10BT - Refer to www.level1.com for most current information. )
