DAVICOM DM9161BEP 芯片, 收发器, 10/100MBPS, 以太网物理层, 48LQFP
The 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 DM9161B connects to the Medium Access Control MAC layer, ensuring a high inter operability from different vendors. The DM9161B uses a low power and high performance advanced CMOS process. It contains the entire physical layer functions of 100BASE-TX as defined by IEEE802.3u, including the Physical Coding Sub layer PCS, Physical Medium Attachment PMA, Twisted Pair Physical Medium Dependent Sub layer TP-PMD, 10BASE-TX Encoder/Decoder ENC/DEC and Twisted Pair Media Access Unit TPMAU. The DM9161B provides a strong support for the auto-negotiation function, utilizing automatic media speed and protocol selection.
