DM9161 series

The DM9161 is a physical layer, single-chip, and lowpower transceiver for 100BASE-TX 100BASE-FX and10BASE-T operations. On the media side, it providesa direct interface either to Unshielded Twisted PairCategory 5 Cable (UTP5) for 100BASE-TX FastEthernet, or UTP5/UTP3 Cable for 10BASE-TEthernet. Through the Media Independent Interface(MII), the DM9161 connects to the Medium AccessControl (MAC) layer, ensuring a high inter-operabilityfrom different vendors.The DM9161 uses a low power and high performanceCMOS process. It contains the entire physical layerfunctions of 100BASE-TX as defined by IEEE802.3u,including the Physical Coding Sublayer (PCS),Physical Medium Attachment (PMA), Twisted PairPhysical Medium Dependent Sublayer (TP-PMD),10BASE-TX Encoder/Decoder (ENC/DEC), andTwisted Pair Media Access Unit (TPMAU). TheDM9161 provides a strong support for theauto-negotiation function, utilizing automatic mediaspeed and protocol selection. Furthermore, due to thebuilt-in wave-shaping filter, the DM9161 needs noexternal filter to transport signals to the media in100BASE-TX or 10BASE-T Ethernet operation
