General Description

DAVICOM’s DM9161B is a physical layer, single-chip, and low power 100BASE-TX/10BASE-T transceiver specifically designed for consumer electronics, industrial and enterprise applications. For the media usage, 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), DM9161B not only connects the Medium Access

Control (MAC) layer but also ensur a high inter operability from different vendors.
