1 / 74 page  LXT970A Dual-Speed Fast Ethernet Transceiver Datasheet The LXT970A is an enhanced derivative of the LXT970 10/100 Mbps Fast Ethernet PHY Transceiver that supports selectable driver strength capabilities and link-loss criteria. The LXT970A supports 100BASE-TX, 10BASE-T, and 100BASE-FX applications. It provides a Media Independent Interface (MII) for easy attachment to 10/100 Media Access Controllers (MAC)s and a pseudo-ECL interface for use with 100BASE-FX fiber networks. The LXT970A supports full-duplex operation at 10 and 100 Mbps. Its operating condition is set using auto-negotiation, parallel detection or manual control. The encoder may be bypassed for symbol mode applications. The LXT970A is fabricated with an advanced CMOS process and requires only a single 5V power supply. The MII may be operated independently with either a 5V or a 3.3V supply. Applications Product Features s Combination 10BASE-T/100BASE-TX Network Interface Cards (NICs) s 10/100 Switches, 10/100 Printservers s 100BASE-FX Network Interface Cards (NICs) s IEEE 802.3 Compliant: — 10BASE-T and 100BASE-TX using a single RJ-45 connection. — Supports auto-negotiation and parallel detection for legacy systems. — MII interface with extended register capability. s Robust baseline wander correction performance. s 100BASE-FX fiber optic capable. s Standard CSMA/CD or full-duplex operation. s Configurable via MII serial port or external control pins. s Configurable for DTE or switch applications. s CMOS process with single 5Vsupply operation with provision for interface to 3.3V MII bus. s Integrated LED drivers. s Integrated supply monitor and line disconnect during low supply fault. s Available in: — 64-pin TQFP (LXT970ATC) — 64-pin PQFP (LXT970AQC) s Commercial temperature range (0 - 70oC ambient). As of January 15, 2001, this document replaces the Level One document Order Number: 249099-001 LXT970A — Dual-Speed Fast Ethernet Transceiver. January 2001 |
