General Description

DAVICOM’s DM9162 is a 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 DM9162 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 DM9162. Then due to the built-in wave shaping filter, the

DM9162 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.
