Enhanced Ethernet Transceiver
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 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
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.
