WJLXT971ALE.A4 Product Details

The Cortina Systems® LXT971A Single-Port 10/100 Mbps PHY Transceiver (LXT971A PHY) 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 PHY is IEEE compliant, and provides a Low Voltage Positive Emitter Coupled Logic (LVPECL) interface for use with 100BASEFX fiber networks. The LXT971A PHY supports full-duplex operation at 10 Mbps and 100 Mbps.
Operating conditions for the LXT971A PHY can be set using auto-negotiation, parallel detection, or manual control. The LXT971A PHY is fabricated with an advanced CMOS process and requires only a single 2.5/3.3 V power supply. (This Datasheet also supports the LXT971 PHY.)
