DM9161
10/100 Mbps Fast Ethernet Physical Layer TX/FX Single Chip Transceiver
1. General Description
The DM9161 is a physical layer, single-chip, and low
power transceiver for 100BASE-TX 100BASE-FX 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 DM9161 connects to the Medium Access
Control (MAC) layer, ensuring a high inter-operability
from different vendors.
The DM9161 uses a low power and high performance
CMOS process. It contains the entire physical layer
functions of 100BASE-TX as defined by IEEE802.3u,
including the Physical Coding Sublayer (PCS),
Physical Medium Attachment (PMA), Twisted Pair
Physical Medium Dependent Sublayer (TP-PMD),
10BASE-TX Encoder/Decoder (ENC/DEC), and
Twisted Pair Media Access Unit (TPMAU). The
DM9161 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 DM9161 needs no
external filter to transport signals to the media in
100BASE-TX or 10BASE-T Ethernet operation.
