General Description

The Am79C98 Twisted-Pair Ethernet Transceiver (TPEX) is an integrated circuit that implements the medium attachment unit (MAU) functions for the twisted-pair medium, as specified by the IEEE 802.3 standard (Type 10BASE-T).

This device provides the necessary electrical and functional interface between the IEEE 802.3 standard attachment unit interface (AUI) and the twisted-pair cable.

A network based on the 10BASE-T standard can use unshielded twisted-pair cables, providing an economical solution to networking by allowing the use of existing telephone wiring.

Overview

FINAL Am79C98 Twisted-Pair Ethernet Transceiver (TPEX) DISTINCTIVE CHARACTERISTICS s CMOS device provides compliant operation and low operating current from a single +5 V supply s Power Down mode provides reduced power consumption for battery-powered applications.

Reset capability allows use in remote MAU applications.

s Pin-selectable twisted-pair receive polarity detection and automatic inversion of the receive signal.

Key Features

  • including pin-selectable TwistedPair Receive Polarity Detection and Automatic Polarity Reversal, Link Status indication, Link Test disable function, and transmit and receive status. The Twisted-Pair Polarity and Link Status pins can be used to drive LEDs directly. The Am79C98 is fabricated in CMOS technology and requires a single +5 V supply. The device is available in 24-pin.
