Small form factor 10/100 ethernet PHY evaluation module


Order now


The DP83825EVM lets designers evaluate the industry’s smallest form-factor, 10BASE-Te/100BASE-TX Ethernet physical layer transceiver, the DP83825I PHY. This evaluation module (EVM) lets designers use one of two interfaces: a network interface through an RJ-45 connector and a MAC interface through a simple multi-pin connector. The EVM is configured and controlled through a USB connection using the USB-2-MDIO simple software tool. The EVM supports interoperability testing, compliance testing and BER testing. The EVM also supports 10BASE-Te and 100BASE-TX Ethernet protocols with header pins that connect to the DP83825i RMII pins.

  • 150-m Cat5 cable reach
  • 100Base-TX, 10Base-Te
  • On-Board MSP430F5529 with USB-2-MDIO for register access
  • Supports interoperability testing, compliance testing and BER testing
