EVB9303

EVB9303 is a Ethernet switch evaluation board that utilizes the LAN9303 to provide a fully functional three port single MII/RMII/Turbo MII Ethernet switch. The EVB9303 provides two fully integrated MAC/PHY Ethernet ports (Ports 1 & 2) via on board RJ45 connectors. Port 0 is connected to external MAC (w/LAN9303 in PHY mode) via onboard 40 pin male MII connector and to external PHY (w/LAN9303 in PHY mode) via onboard 40 pin female MII connector. Power is supplied to the board via a 5V external wall mount power supply. The external supply is not necessary when Port 0 is configured for (and used in) PHY mode. In such cases, the 5V power rail is typically supplied through the MII connector from the MAC side. The EVB9303 includes a 8K x 8 I2C EEPROM that may be used to automatically load configuration settings from the EEPROM into the device at reset, allowing the device to operate unmanaged. An I2C host adapter interface header (10 pin, 2x5) is provided to simplify I2C based configuration.
