DM9161: 10/100 Fast Ethernet Physical Layer TX/FX Single Chip Transceiver

 

The DM9161 is a physical-layer single chip low power transceiver for 10Base-T, 100Base-TX and 100FX operations. The identical PHY Core is also being used in the MAC/PHY Controller DM9000.
It provides a strong support for the auto-negotiation function utilizing media speed and full-/half-duplex protocol selection. Due to the built-in wave-shaping filter, the DM9161 does not need any external filters to transport signals to the media in 100M or 10M Ethernet operations. Through the Media Independent Interface (MII), the DM9161 connects to the Medium Access Control (MAC) layer, ensuring a high inter-oparability among products from different vendors. The DM9161 uses a low-power and high-performance 3.3V CMOS process with 5V tolerant I/Os. It contains the entire physical layer functions of 100BASE-Tx as defined by IEEE802.3u:

  • Pysical 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)

The power-down mode, selectacle 1:1 or 1.25 :1 TX-driver allows further savings in power consumption.
