DM9111A: 10/100 Mbit Fast Ethernet Physical Layer TX/FX Single Chip Transceiver


DM9111A is the newest member of the Davicom Single PHY Transceiver family.
Its main advantages are:
- low cost due to 0,11µ process. Resale price at 10k pieces is 0,36 USD / piece
- Very low power consumption modes <165mW
- RMII in a small QFN-24 package
- 50MHz clock out at RMII applications which can save BOM cost and design efforts at the system designer
- IEEE802.3az
- 2.5V/1.8V IO

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 DM9111A needs no external filter to transport signals to the media in 100BASE-TX or 10BASE-T Ethernet operation.
