2. General Description

DAVICOM’s DM9161C is a physical layer, low

power, and single-chip 10BASE-T/100BASE-TX

transceiver specifically designed for consumer

Through its Media Independent Interface (MII),

the DM9161C 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 DM9161C 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 DM9161C 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

electronics,

industrial,

and

enterprise

applications. Through using a CMOS process,

the DM9161C 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 DM9161C.

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

DM9161C 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.

Encoder/Decoder

(ENC/DEC), and Twisted Pair Media Access

Unit (TPMAU).
