DM9161BIEP

DAVICOM  DM9161BIEP  以太网控制器, 100 Mbps, IEEE 802.3, IEEE 802.3u, 3.135 V, 3.465 V, LQFP, 48 引脚

The is a 10/100Mbps fast Ethernet physical layer single-chip and Low Power Transceiver for 100BASE-TX and 10BASE-T operations. Supports industrial-grade from -40 to +85°C, 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 DM9161BI connects to the Medium Access Control MAC layer, ensuring a high inter operability from different vendors. TheDM9161BI 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 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.
