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 MC68160B gluelessly interface to the
Ethernet controller contained in the MC68360 Quad Integrated
Communications Controller (QUICC) device. The MC68160B 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.
** MC68160AB does not support all IEEE 802.3 specifications over extended
