IP175C: 5 Port 10/100 Ethernet Integrated Switch

IP175C:LAN以太网芯片的详细介绍

general desc-ription　

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 duplex, and it is also able to configure to 100base-fx transmission mode. using an eeprom or pull up/down resistors on specified pins can configure the desired options.

ip175c supports three mii/rmii ports for more application, which supports 4 lan ports, one wan port and one home/pna or access point. mii0/rmii0 and mii2/rmii2 is for lan traffic and mii1/rmii1 is for wan traffic and no external phy is needed. both mii/rmii work in phy mode and interface to the external mac in this application. the external mac can monitor or configure ip175c by accessing mii registers through smi0.

mii0 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.
