3 Description

The DP83825I is an ultra small form factor, very

low power Ethernet Physical Layer transceiver with

integrated PMD sublayers to support 10BASE-Te,

100BASE-TX Ethernet protocols. The PHY supports

up to 150 meters reach over CAT5e cable. The

DP83825I interfaces directly to twisted pair media via

an external transformer.

The DP83825I also supports Energy Efficient

Ethernet, Wake-on-LAN and MAC isolation to further

lower the system power consumption. Energy Efficient

Mode can be enabled through register configuration

for legacy MACs not supporting EEE signaling over

MAC. DP83825I can operate in unmanaged repeater

mode. In this mode, DP83825I works as a repeater

without register configuration. The DP83825I offers

integrated cable diagnostic tools, built-in self-test and

loopback capabilities for ease of development and

debug.
