DM9161BIEP Datasheet PDF - Davicom Semiconductor

●The DM9161BIEP 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).
