Block Diagam DM9163

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.
