Gigabit PHY IC Complies With Energy-Efficient Ethernet Guidelines

The XWAY PHY11G Gigabit PHY IC complies with the Energy Efficient Ethernet (EEE) guidelines, which are based on the upcoming IEEE 802.3az standard. It reduces its energy use by up to 90% (50 mW instead of 500 mW) during idle periods. Most current Gigabit PHY ICs do not have this low-power mode. When operating under full load, the PHY11G consumes at least 25% less energy compared to existing solutions, spending less than 400mW in total. The XWAY PHY11G family includes single-port Gigabit Ethernet (GbE) PHY ICs supporting half- and full-duplex modes at 10base-T, 10base-Te, 100base-TX, 1000base-T, and 1000base-X. Devices are manufactured in 65-nm process technology and available in two small packages: the 7-mm x 7-mm VQFN-48 and the 12-mm x 12-mm LQFP-64 package. The devices operate from a 2.5-V to 3.3-V power-supply. Infineon also offers the XWAY PHY22F, a dual-port Fast Ethernet PHY with the same EEE features. Samples of the XWAY PHY11G and XWAY PHY22F will be available in the fourth quarter of 2009, while volume production is expected to start in the first quarter of 2010.
