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.

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.
