2. General Description

the DM9161CI not only connects the Medium

Access Control (MAC) layer, but the MII also

ensure a high inter-operability and flexibility with

different vendors. In media usage applications,

the DM9161CI provides a direct interface either

to an Unshielded Twisted Pair Category 5 Cable

(UTP5) for 100BASE-TX Fast Ethernet, or an

UTP5/UTP3 Cable for 10BASE-T Ethernet.

The DM9161CI contains the entire physical layer

functions of 100BASE-TX. Those physical layer

functions are defined by IEEE802.3u include the

Physical Coding Sub layer (PCS), Physical

Medium Attachment (PMA), Twisted Pair

Physical Medium Dependent Sub layer

DAVICOM’s DM9161CI is

industrial-

temperature physical layer, low power, and

single-chip 10BASE-T/100BASE-TX transceiver

specifically designed for consumer electronics,

industrial, and enterprise applications. Through

using a CMOS process, the DM9161CI has the

advantage of ensuring both high performance

and savings in power consumption.

Through utilization of automatic media speed

and protocol selection, the auto-negotiation

function is strongly supported in the DM9161CI.

Then due to the built-in wave shaping filter, the

DM9161CI has a significant convenience of not

requiring an external filter to transport signals to

the media in 10BASE-T or 100BASE-TX during

Ethernet operation.

(TP-PMD),

10BASE-TX

Encoder/Decoder

(ENC/DEC), and Twisted Pair Media Access

Unit (TPMAU).

Through its Media Independent Interface (MII),
