LAN9311 Datasheet PDF - SMSC -> Microchip

General Description
   The LAN9311/LAN9311i is a full featured, 2 port 10/100 managed Ethernet switch designed for embedded applications where performance, flexibility, ease of integration and system cost control are required. The LAN9311/LAN9311i combines all the functions of a 10/100 switch system, including the switch fabric, packet buffers, buffer manager, media access controllers (MACs), PHY transceivers, and host bus interface. The LAN9311/LAN9311i complies with the IEEE 802.3 (full/half-duplex 10BASE-T and 100BASE-TX) Ethernet protocol specification and 802.1D/802.1Q network management protocol specifications, enabling compatibility with industry standard Ethernet and Fast Ethernet applications.
