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.

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

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.

The DM9161 uses a low power and high performance

CMOS process. It contains the entire physical layer
