Table 2-1 EVM Applications
NO. DP83825 MODE APPLICATIONS HOW TO USE
1 RMII to Copper Run traffic between RMII and Copper. Connect to DP83822 EVM or MAC System using Header pins.
Perform IEEE and UNH compliance testing Using onboard MSP430 and software.
Run EMI/EMC Test on EVM Use internal PRBS and loopback. MSP430 launchpad can be used for register access.
Measure Power Dissipation Connect external power supplies.
External MAC loopback Connect external MAC to headers and use MAC loopback register settings
50 MHz output clock Optional Clock out SMA
2 RMII Loopback Data received by the PHY can be looped back through the RMII interface without needing a MAC. Use jumpers to connect TXD0->RXD0, TXD1->RXD1, and TXEN->RXDV.
3 Repeater Mode RMII back to back as range extender. Two EVMs can be connected back to back using custom header cable.
4 Low Power modes Demonstrate EEE Straps to enable EEE.
Demonstrate Sleep and Power down mode Use MSP430 launchpad to activate low power mode
