Product Overview

The DM9161EP is a 10/100 Mbps Fast Ethernet physical layer TX/FX Single Chip Transceiver for 100BASE-TX 100BASE-FX 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 DM9161 connects to the Medium Access Control (MAC) layer, ensuring a high inter-operability from different vendors. The DM9161 uses a low power and high performance 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).
  • Fully complies with IEEE 802.3u

  • Selectable GPSI (7-wired) or MII mode at the 10Base-T
  • Selectable twisted-pair or fibre mode output
  • Selectable full-duplex or half-duplex operation
  • MII management interface with maskable interrupt output capability
  • Provides loopback mode for easy system diagnostics
  • LED status outputs indicate link/activity, speed 10/100 and full-duplex/collision
  • Single low power supply of 3.3V with 0.35μm CMOS technology
  • Compatible with 3.3 and 5.0V tolerant I/Os
ESD sensitive device, take proper precaution while handling the device.
