DM9161 General Description
The DM9161 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 DM9161 connects to the Medium Access Control (MAC) layer,ensuring a high inter operability from different vendors.
The DM9161 uses a low power and high performance CMOS process. It contains the entire physical layer functions of 100BASE-TX as defined by IEEE802.3u,including the Physical Coding Sublayer (PCS),Physical Medium Attachment (PMA), Twisted Pair Physical Medium Dependent Sublayer (TP-PMD),10BASE-TX Encoder/Decoder (ENC/DEC), and Twisted Pair Media Access Unit (TPMAU). The DM9161 provides a strong support for the auto-negotiation function, utilizing automatic media speedand protocol selection. Furthermore, due to the built-in wave shaping filter, the DM9161 needs no external filter to transport signals to the media in 100BASE-TX or 10BASE-T Ethernet operation.
