General Description
The SMSC LAN83C185 is a low-power, highly integrated analog
interface IC for high-performance embedded Ethernet applications.
The LAN83C185 requires only a single +3.3V supply.
The LAN83C185 consists of an encoder/decoer, scrambler/descrambler,
transmitter with wave-shaping and output driver, twisted-pair
receiver with on-chip adaptive equalizer and baseline wander
(BLW) correction, clock and data recovery, and Media Independent
Interface (MII).
The LAN83C185 is fully compliant with IEEE 802.3/802.3u standards
and supports both 802.3u-compliant and vendor-specific register
functions. It contains a full-duplex 10BASE-T/100BASE-TX transceiver
and supports 10 Mbps (10BASE-T) operation on Category 3 and
Category 5 unshielded twisted-pair cable, and 100 Mbps (100BASE-TX)
operation on Category 5 unshielded twisted-pair cable.
