IP178CH General Description

IP178C/IP178CH integrates a 9-port switch controller, SSRAM, and 8 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 in 0.18um technology; they have high noise immunity and robust performance.

IP178C/IP178CH 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 as auto-negotiation or forced 10 Mbps/100 Mbps, full/half duplex mode. Using an EEPROM or pull up/down resistors on specific pins can configure the desired options.

Besides an 8-port switch application, IP178C/IP178CH 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/IP178CH 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.

IP178CH Typical Application

` An 8-port switch application
    - If pin 53 EXTMII_EN is pulled low, then MII/ RMII interface is disabled. IP178C/IP178CH is not connected to a CPU and works as an 8-port switch. The ninth switch port MAC8 is unused in this application.
` A 9-port switch application
    - If pin 53 EXTMII_EN is pulled high, then MII/ RMII interface is enabled. The ninth switch port MAC8 is connected to a PHY through the MII/RMII interface. IP178C/IP178CH works as a 9-port switch. Because IP178C/IP178CH doesn't access the MII register of the external PHY through SMI, MII/RMII interface should be MAC mode and full duplex in this application.
` An 8-port router application
    - IF pin 53 EXTMII_EN is pulled high, then MII/RMII interface is enabled. IP178C/IP178CH is connected to a CPU through MII/ RMII interface. IP178C/IP178CH works as an 8-port router. MII/RMII interface is set to be PHY mode and 100 Mbps full duplex in this application.
