Fast Ethernet Chip Embraces 3.3V PHY Layer

This single chip, 3.3V Fast Ethernet Physical Layer solution integrates a 10/100-Mbps transceiver with the Physical Signaling and Physical Coding sublayers to implement all required functions between the line isolation magnetics and the Ethernet Media Access Controller (MAC). The LAN83C183 IC connects to the MAC via an industry-standard MII interface that supports 10BaseT, 100BaseTX and 100BaseFX Ethernet media for copper or fiber media.
