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. It supports up to 150 meters reach over CAT5e cable. The DP83825I interfaces directly to twisted pair media via an external transformer. It interfaces to the MAC layer through Reduced MII (RMII) both in Master and Slave mode. It provide 50-MHz output clock in RMII Master Mode. This clock is synchronized to MDI derived clock to reduce the jitter in the system.

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 un-managed 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.
