General Description : 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. Feature : 8 port Embedded 10/100 PHY Switch Controller Support 8 100BaseTX or 6 100Base TX + 2 FX Support Auto MDI-MDIX function Power Management Tool (PWMT®) - APS, auto-power saving while Link-off - IEEE 802.3az protocol based power saving & 10Mbps Te for 10Mbps - WOL+®, light traffic power saving - PWD, force-off power saving Support Auto Factory Test (AFT®) Single Power 3.3V supply Built in Vcore Regulator Two Priority queues per port Support 802.1p & DiffServ based QoS QoS - Port base - 802.1p - IP DiffServ IPV4/IPV6 - TCP/UDP port number - Pins configure ports priority (VIP port) Support max forwarding packet length 1552/1536 bytes option Support port mirror function Support 1k MAC address Support broadcast storm protection Support port trunking (LACP) Support 16 VLAN (IEEE Std 802.1q) - Port-based/Tagged-based VLAN - Support insert, remove tag Built-in 50 ohm resistors for simplifying BOM 85nm Process Package and operation temperature IP178G: 68 Pin QFN, 0~70℃
