5 Port 10/100 Ethernet Integrated Switch

IP175A LF is a low cost 10/100 Ethernet single chip Switch It integrates a 5-port Switch controller, SSRAM, and 5 10/100 Ethernet Transceivers Each of the transceivers complies with the IEEE802.3, IEEE802.3u, and IEEE802.3x specifications. The transceivers are designed in DSP approach with 0.25um technology; they have high noise immunity and robust performance. IP175A LF operates in store and forward mode. It supports flow control, auto MDI/MDI-X, CoS, port base VLAN, and LED functions, etc. Each port CAN be configured to auto-negotiation or forced 10M/100M, full/half duplex, and it is also able to configure to 100BaseFX transmission mode. Using an EEPROM or pull up/down resistors on specified pins CAN configure the desired options. IP175A LF does not support forced 10M half mode. IP175A LF supports two MII ports for router application, which supports 4 LAN ports and one WAN port. MII0 is for LAN traffic and MII1 is for WAN traffic and no external PHY is needed. Both MII CAN work in PHY mode and Interface to the external MAC in this application. The external MAC CAN monitor or configure IP175A LF by accessing MII Registers through SMI. MII0 also CAN be configured to be MAC mode. It is used to Interface an external PHY to work as a 4+1 Switch By Unkown
