GENERAL DESCRIPTION  
The Am79C100 Twisted-Pair Ethernet Transceiver Plus  
(TPEX Plus) is an integrated circuit that implements the  
medium attachment unit (MAU) functions for the  
twisted-pair medium, as specified by the supplement to  
the IEEE 802.3 standard (Type 10BASE-T). This de-  
vice provides the necessary electrical and functional  
interface between the IEEE 802.3 standard attachment  
unit interface (AUI) and the twisted-pair cable.  
TPEX Plus provides twisted-pair driver and receiver cir-  
cuits, including on-board transmit digital predistortion,  
receiver squelch, and an AUI port with pin-selectable  
SQE Test enable. The device provides a number of ad-  
ditional features, including Link Status indication with  
automatic twisted-pair receive polarity detection/  
correction and indication; pin-selectable receive  
threshold programming for extended distance line  
lengths; and Receive Carrier Sense, Transmit Active  
and Collision Present indications. The device provides  
separate twisted-pair Link Status, Polarity Status,  
Receive, Transmit, and Collision outputs to drive LEDs  
directly.  
A network based on the 10BASE-T standard can use  
unshielded twisted-pair cables, providing an economi-  
cal solution to networking by allowing the use of existing  
telephone wiring. The Am79C100 provides a minimal  
component count and a cost-effective solution to the  
design and implementation of 10BASE-T standard  
networks.
