IP175C 5-port 10/100M Ethernet Integrated Switch

IP175C integrates a 6-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 0.18um technology; they have high noise immunity and robust performance.

IP175C operates in store and forward mode. It supports flow control, auto MDI/MDI-X, CoS, port base VLAN, bandwidth control, DiffServ, SMART MAC and LED functions, etc. Each port can be configured to auto-negotiation or forced 10M/100M, full/half duplexmode. Using an EEPROM or pull up/down resistors on specified pins can configure the desired options.

Besides a 5-port switch application, IP175C supports three MII/RMII ports for router application, which supports 4 LAN ports, one WAN port and one HOME/PNA or Access point. The external MAC can monitor or configure IP175C by accessing MII registers through SMI0.

MII/RMII port also can be configured to be MAC mode. It is used to interface an external PHY to work as a 5+1 switch. Through SMI1 IP175C can monitor and configure external PHY
