2.1.1 EVM High-Level Summary

The DP83869EVM supports SMI through J15 using pin 26 for MDIO and 28 for MDC. These pins can be connected to an MSP430 Launchpad, which can be used for USB-2-MDIO control.

Table 2-1 EVM Applications
NO. DP83869 MODE APPLICATIONS HOW TO USE
1 RGMII to Copper Run traffic between RGMII and Copper. Connect to DP83867 RGMII EVM or MAC System using Header pins/Samtech connector.
Perform IEEE and UNH compliance testing Use onboard MSP430 to activate test mode waveform on DP83869.
Run EMI/EMC Test on EVM Use internal PRBS and loopback.
Measure Power Dissipation Connect external power supplies.
External MAC loopback Connect external MAC to headers/Samtech connector.
2 SGMII to Copper Run traffic between SGMII and Copper. Connect to DP83867 SGMII EVM or MAC System using SMA connector.
Perform IEEE and UNH compliance testing Use onboard MSP430 to activate test mode waveform on DP83869.
Run EMI/EMC Test on EVM Use internal PRBS and loopback.
External SGMII loopback Use SMA cable for Passive Loopback.
