Order this document by MC68160/D Enhanced Ethernet Transceiver The MC68160, B and C Enhanced Ethernet Interface Circuit is a BiCMOS device which supports both IEEE 802.3* Access Unit Interface (AUI) and 10BASE–T Twisted Pair (TP) Interface media connections through external isolation transformers. It encodes NRZ data to Manchester data and supplies the signals which are required for data communication via 10BASE–T or AUI interfaces. The MC68160, B and C gluelessly interface to the Ethernet controller contained in the MC68360 Quad Integrated Communications Controller (QUICC) device. The MC68160 also interfaces easily to most other industry–standard IEEE 802.3 LAN controllers.** Prior to twisted pair data reception, Smart Squelch circuitry qualifies input signals for correct amplitude, pulse width, and sequence requirements.
