This document is about the technical data of MC68160A/D device, it is a BiCMOS device that 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 that are required for data communication via 10BASE-T or AUI interfaces. MC68160A gluelessly interface to the Ethernet controller contained in the MC68360 Quad Integrated Communications Controller (QUICC) device. MC68160A 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.
This datasheet describes the MC68160A Enhanced Ethernet Interface Circuit, a BICMOS device that supports both IEEE 802.3 AUI and 10BASE‑T twisted‑pair media. It details the encoding of NRZ data to Manchester, the various optional features such as automatic polarity correction, link integrity testing, and full‑duplex operation, and the interface to Ethernet controllers like the MC68360 QUICC.
The document includes pin‑function tables, electrical characteristics, maximum ratings, recommended operating conditions, and ESD protection information, as well as application notes for crystal selection, external components, and mode selection.
