SNLS638A December 2018 – August 2019 DP83825I
Energy Efficient Ethernet (EEE), defined by IEEE 802.3az, is a capability integrated into Layer 1 (Physical Layer) and Layer 2 (Data Link Layer) to operate in Low Power Idle (LPI) mode. In LPI mode, power is saved during periods of low packet utilization. EEE defines the protocol to enter and exit LPI mode without dropping the link or corrupting packets.
The DP83825I EEE supports 100-Mbps and 10-Mbps speeds. In 10BASE-Te operation, EEE operates with a reduced transmit amplitude that is fully interoperable with a 10BASE-T PHY.
