10/100 Ethernet PHYs are low power

The LAN8740, LAN8741 and LAN8742 10/100 Ethernet PHY ICs offer up to 50% lower power consumption than their predecessors. The LAN874x family also features cable diagnostics and deterministic loop back delay.

ICDJH03_Sms_1_Sep2012

The LAN8740 and LAN8741 implement the IEEE 802.3az Energy Efficient Ethernet standard directly into the physical layer and the LAN8742, while not IEEE compatible, implements a “wake on LAN” mode. They come in a 32-pin SQFN 5 x 5 x 0.9 mm package in commercial or industrial temperature ranges. ($0.69 to $0.95 ea/volume qty — samples available now.)
