Ethernet MAC
The LC82161B provides two on-chip 10/100 Mbps Ethernet MAC circuits. The IC connects to an external PHY using an
MII interface. MAC1 is for use in a WAN, and MAC2 for use in a LAN. Flow control between the two MACs is controlled
by the protocol engine.
Data rate: 10 or 100 Mbps
MII interface with an external PHY
Frame generation, CRC generation and checking
Address filtering
— Unicast and multicast support
Full-duplex and half-duplex operation
Flow control (in full-duplex mode)
— Pause frame generation
CSMA/CD protocol (in half-duplex mode)
— Collision detection and automatic resend
VLAN support
