Enhanced Ethernet Transceiver

MC68160A

The MC68160A Enhanced Ethernet Interface Circuit is a BiCMOS device which supports both IEEE Access Unit Interface AUI and 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 or AUI interfaces. The MC68160A gluelessly interface to the Ethernet controller contained in the MC68360 Quad Integrated Communications Controller QUICC device. The MC68160A also interfaces easily to most other IEEE LAN controllers. Prior to twisted pair data reception, Smart Squelch circuitry qualifies input signals for correct amplitude, pulse width, and sequence requirements.
