DM9163: 10/100 Mbit Fast Ethernet Physical Layer TX Single Chip Transceiver

The DM9163 is a physical layer, single-chip with industrial temperature standard, and low power transceiver for 100BASE-TX and 10BASE-T operations. On the media side, it provides a direct interface to either 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 DM9163 connects to the Medium Access Control (MAC) layer, ensuring a high interoperability from different vendors.

Features

  • LQFP-48 package
  • 8kV Isolation Voltage
  • 3.3V transformer at Center Tap
  • Current consumption 90mA + 40mA (transformer)
  • 50MHz RMII clock output
  • Auto MDI-X
  • 0.18 µm Process
  • LED Status (Link/Activity, Speed, Full Duplex/Collision)
  • Full-Duplex or Half-Duplex
  • Compatible to IEEE802.3u
  • MII and Reverse MII
  • SPI EEPROM Interface
  • Integrated 3.3V to 1.8V regulator
  • Temperature Range: -40° to 85°C

DM9163 is an enhanced version of DM9162 focusing on industrial applications.

.

Its main advantages are:

- 50MHz clock out at RMII applications which can save BOM cost and design efforts at the system designer
- 8kV isolation voltage
- 3.3V transformer at CT

DM9163 is backward compatible to DM9161A and DM9162.
It contains the entire physical layer functions of 100BASE-TX as defined by IEEE802.3u:

  • Physical Coding Sublayer (PCS)
  • Physical Medium Attachement (PMA)
  • Twisted Pair Physical Medium Dependent Sublayer (TP-PMD)
  • 10Base-TX Encoder/Decoder (ENC/DEC) 
  • Twisted Pair Media Access Unit (TPMAU)

Furthermore, due to the built-in wave shaping filter, the DM9163 needs no external filter to transport signals to the media in 100BASE-TX or 10BASE-T Ethernet operation.
