10/100 Mbit MDI-X Fast
Ethernet PHY Transceiver
The DM9161C is a 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 DM9161C connects
to the Medium Access Control (MAC) layer, ensuring a high inter operability
from different vendors.
The DM9161C is the improved version of the DM9161B with optimized consuption
in 10Base-T mode and the Speed-LED probleme has been fixed. The DM9161C
is 100% pin- and software compatible to the DM9161A. Additionally to the
48pin LQFP package a 32pin QFN package is available.
The DM9161C 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, including the Physical Coding Sub layer (PCS), Physical
Medium Attachment (PMA), Twisted Pair Physical Medium Dependent Sub layer
(TP-PMD), 10BASE-TX Encoder/Decoder (ENC/DEC), and Twisted Pair Media
Access Unit (TPMAU). The DM9161C 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 DM9161C needs no external
filter to transport signals to the media in 100BASE-TX or 10BASE-T Ethernet
operation.
