Smallest form factor (3-mm by 3-mm), low-power 10/100-Mbps Ethernet PHY transceiver with 50-MHz c

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.
