General Description
IP178C integrates a 9-port switch controller, SSRAM, and 8 10/100 Ethernet transceivers. Each of the transceivers plies with the IEEE802.3, IEEE802.3u, and IEEE802.3x specifications. The transceivers are designed in DSP approach in 0.18um technology; they have high noise immunity and robust performance. IP178C operates in store and forward mode. It supports flow control, auto MDI/MDI-X, Co S, port base VLAN, bandwidth control, Diff Serv, SMART MAC and LED functions, etc. Each port can be configured as auto-negotiation or forced 10 Mbps/100 Mbps, full/half duplexmode. Using an EEPROM or pull up/down resistors on specific pins can configure the desired options. Besides an 8-port switch application, IP178C supports one MII/RMII ports for router application, which supports 7 LAN ports and one WAN port. The external MAC can monitor or configure IP178C by accessing MII registers through SMI. MII/RMII port also can be configured to be MAC mode. It is used to interface an external PHY to work as an 8+1 switch. w w w
