N0.TEST CASESAPPLICATIONSHOW TO USE
1MII/RMII to CopperRun traffic between MII/RMII and Copper.Connect to DP83826 EVM or MAC System using Header pins.
Perform IEEE and UNH compliance testingUsing onboard MSP430 and software.
Run EMI/EMC Test on EVMUse internal PRBS and loopback. Onboard MSP430 can be used for register access.
Measure Power DissipationConnect external power supplies.
External MAC loopbackConnect external MAC to headers and use MAC loopback register settings
50MHz output clockOptional Clock out SMA
2LoopbackData received by the PHY can be looped back through the interface without needing a MAC.Use onboard MSP430 to enable loopback.
3Repeater ModeRMII back to back as range extender.Two EVMs can be connected back to back using custom header cable.
4Low Power modesDemonstrate EEEUse onboard MSP430 to enable EEE.
Demonstrate Sleep and Power down modeUse onboard MSP430 to activate low power mode
