DM9161AEP 托盘

General Description

The DM9161A is a physical layer, single-chip, and low power transceiver for 100BASE-TX 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 DM9161A connects to the Medium Access Control MAC layer, ensuring a high inter operability from different vendors.
