The SMSC LAN83C183 is a highly integrated analog interface IC for twisted pair Ethernet applications.
The LAN83C183 can be configured for either 100-Mbps (100BASE-TX or 100 BASE-FX) or 10-Mbps
(10BASE-T) Ethernet operation. The 100BASE-FX is packaged in a 64-Pin TQFP pack-age.
The LAN83C183 consists of a 4B5B/Manchester encoder/decoder, scrambler/descrambler, transmitter
with wave shaping and output driver, twisted pair receiver with on-chip equalizer and baseline wander
correction, clock and data recovery, AutoNegotiation, controller interface (MII), and serial port (MI).
The addition of internal output waveshaping circuitry and on-chip filters eliminates the need for external
filters normally required in 100BASE-TX and 10BASE-T applications.
The LAN83C183 can automatically configure itself for 100- or 10-Mbps and full- or half-duplex operation
with the on-chip AutoNegotiation algorithm.
The eleven 16-bit registers of the LAN83C183 can be accessed through the Management Interface (MI)
serial port. These registers contain configuration inputs, status outputs, and device capabilities.
The LAN83C183 is ideal as a media interface for 100BASE-TX/10BASE-T adapter cards, PC Cards,
motherboards, mobile applications, repeaters, switching hubs, and external PHYs.
The LAN83C183 operates from a single 3.3V supply. All inputs and outputs are 5V-tolerant and can
directly interface to other 5V devices.
