Low power Ethernet physical layer transceiver

The DP83825I from Texas Instruments is the smallest form factor, lowest power Ethernet Physical Layer transceiver with integrated PMD sublayers to support 10BASE-Te, 100BASE-TX Ethernet protocols. 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. 

The 50MHz clock in RMII Master mode is synchronised to MDI derived clock to reduce the jitter in the system.

The DP83825I offers integrated cable diagnostic tools, built-in self-test and loopback capabilities for ease of use. It supports multiple industrial buses with its fast link-down timing.

The DP83825I also supports Energy Efficient Ethernet, Wake on LAN and MAC isolation to further lower the system power consumption. DP83825I can operate in unmanaged repeater mode. In this mode, DP83825I works as a repeater without register configuration.
