The DM9161 is a physical layer, single-chip, and low power transceiver for 100BASE-TX 100BASE-FX and 10BASE-T operations. On the media side, it provides a direct interface either to Unshielded Twisted Pair Category 5 Cable (UTP5) for 100BASE-TX Fast Ethernet, or UTP5/UTP3 Cable for 10BASE-T Ethernet. Through the Media Independent Interface (MII), the DM9161 connects to the Medium Access Control (MAC) layer, ensuring a high inter-operability from different vendors.
