The MC68160 is an enhanced Ethernet interface transceiver that supports both IEEE 802.3 AUI and 10BASE-T TP interface media connections. It encodes NRZ data to Manchester data and provides the signals required for data communication via 10BASE-T or AUI interfaces. The MC68160 interfaces seamlessly with the Ethernet controller contained in the MC68360 Quad Integrated Communications Controller (QUICC) device. It also interfaces easily to most other industry-standard IEEE 802.3 LAN controllers.
This document is a technical data sheet for the MC68160, B, and C Enhanced Ethernet Interface Circuit. It describes a BiCMOS device that supports both IEEE 802.3 Access Unit Interface (AUI) and 10BASE-T Twisted Pair Interface media connections through external isolation transformers.
