LAN83C185-JT

The Microchip 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/decoder, 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.
