Hot-selling and scarce DM9161BIEP Fast Ethernet Physical Layer Single Chip Transceiver IC QFP spot stock

Product Descriptions

The DM9161BI is a Industrial-grade physical layer,single-chip,  and  low  power  transceiver  for100BASE-TX and 10BASE-T operations . On themedia side,it provides a direct interface either toUnshielded Twisted Pair Category 5 Cable (UTP5)for100BASE-TX Fast Ethernet,or UTP5/UTP3 Cable for10BASE-T Ethernet .Through the Media IndependentInterface (MII),the DM9161BI connects to the MediumAccess Control (MAC)layer,ensuring a high interoperability from different vendors .

The DM9161BI uses a low power and highperformance advanced CMOS process .It contains the​ Entire physical layer functions of 100BASE-TX asdefined by IEEE802 .3u,including the Physical CodingSub 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 DM9161BI provides a strong supportfor the auto-negotiation function,utilizing automaticmedia speed and protocol selection .Furthermore,dueto the built-in wave shaping filter,the DM9161BI needsno external filter to transport signals to the media in100BASE-TX or 10BASE-T Ethernet operation .
