The DM9161AEP 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 DM9161AEP connects to the Medium Access Control (MAC) layer, ensuring a high inter operability from different vendors. The DM9161AEP 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). The DM9161AEP provides a strong support for the auto-negotiation function, utilizing automatic media speed and protocol selection. Furthermore, due to the built-in wave shaping filter, the device needs no external filter to transport signals to the media in 100BASE-TX or 10BASE-T Ethernet operation.



DM9161AEP absolute maximum ratings: (1)Supply Voltage:-0.3V to 3.6V ; (2)DC Input Voltage (VIN):-0.5V to 5.5V ; (3)DC Output Voltage(VOUT):-0.3V to 3.6V ; (4)Storage Temperature Rang (Tstg):-65℃ to +150℃; (5)Case Temperature:0℃ to 85℃; (6)Lead Temp. (TL, Soldering, 10 sec.):260℃.
