IP178G/GI数据手册IC+中文资料规格书

描述 Description

IP178Gx is fabricated with advanced CMOS (85nm) technology and only requires a 3.3V single power supply. This feature makes IP178GX used very low power consumption, such as the full load operation (100Mbps full duplex 8 ports), it only takes 0.95W.
 IP178Gx also supports Power Management Tool (PWMT®) for IEEE 802.3az, APS, WOL+ and PWD for Green Power. While two link devices have no IEEE 802.3az capability, IP178Gx use WOL+ to change the link from 100Mbps to 10Mbps for saving power.
 The PWD, force-off power saving of IP178Gx is designed for power down switch immediately by pushing a button, user don’t plug out the power adapter. Push the button again, it will power on immediately.
 Low Power and Rich Power Saving method, IP178Gx supports AFT® for saving Customer Testing Cost. By using a push button and cables, IP178Gx will Auto test completely by itself.
