DM9161BI Industrial-grade 10/100 Mbps Fast Ethernet Physical Layer Single Chip Transceiver
The DM9161BI is a Industrial-grade physical layer, single-chip, and low power transceiver for 100BASE-TX and 10BASE-T operations. On the media side, it provides a direct interface either to 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 DM9161BI connects to the Medium Access Control (MAC) layer, ensuring a high inter operability from different vendors.
Features
The DM9161B is a physical layer, single-chip, and low power transceiver for 100BASE-TX and 10BASE-T operations. It supports HP´s Auto MDI-X feature and is available in commercial and industrial temperature range.

On the media side, it provides a direct interface either to 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 DM9161B connects to the Medium Access Control (MAC) layer, ensuring a high interoperability from different vendors.
The DM9161B uses a low power and high performance advanced CMOS process.
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)
The DM9161B provides a strong support for the auto-negotiation function, utilizing automatic media speed and protocol selection.
Furthermore, due to the built-in wave shaping filter, the DM9161B needs no external filter to transport signals to the media in 100BASE-TX or 10BASE-T Ethernet operation.
