AM79C98 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.The Am79C98 provides a minimal component count and cost-effective solution to the design and implementation of 10BASE-T standard networks.
TPEX provides twisted-pair driver and receiver circuits, including on-board transmit digital predistortion, receiver squelch, and an AUI port with pin-selectable SQE Test enable.The device also provides a number of additional features, including pin-selectable Twisted-Pair 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 SKINNYDIP® plastic dual in-line and 28-pin plastic leaded chip carrier (PLCC) packaging
