供应IP178G 6+2以太网与光纤交换机芯片与方案（IP178G 8 Port 10/100M Ethernet Integrated Switch

IP178G is fabricated with advanced CMOS (85nm/Low Power) technology and only requires a 3.3V single power supply for saving BOM cost. This feature makes IP178G consumes very low power, such as the full load operation (100Mbps_FDX x8) and embedded LDO, overall power consumption only takes 0.87w.                               
IP178G 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, IP178G use WOL+ to change link from 100Mbps to 10Mbps for saving power.
The PWD of IP178G 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.
Except Low Power and Rich Power Saving method, IP178G supports AFT? for saving Customer Testing Cost. By using a push bottom and cables, IP178G will Auto test completely by itself.
