DM9161CI series

DAVICOM's DM9161CI is a industrial-temperature physical layer, low power, and single-chip 10BASE- T/100BASE-TX,100BASE-FX transceiver specifically designed for consumer electronics, industrial, and enterprise applications. Through using a CMOS process, the DM9161CI has the advantage of ensuring both high performance and savings in power consumption. Through utilization of automatic media speed and protocol selection, the auto-negotiation function is strongly supported in the DM9161CI. Then due to the built-in wave shaping filter, the DM9161CI has a significant convenience of not requiring an external filter to transport signals to the media in 10BASE-T or 100BASE-TX during Ethernet operation. Through its Media Independent Interface (MII), the DM9161CI not only connects the Medium Access Control (MAC) layer but also ensure a high inter- operability and flexibility for our different vendors. In media usage applications, the DM9161CI provides a direct interface either to an Unshielded Twisted Pair Category 5 Cable (UTP5) for 100BASE-TX Fast Ethernet, or an UTP5/UTP3 Cable for 10BASE-T Ethernet. The DM9161CI contains the entire physical layer functions of 100BASE-TX. Those physical layer functions are defined by IEEE802.3u include 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).
