Applications

The EVB8700 Evaluation board simplifies the process of testing and evaluating an Ethernet Connection in your appli-

cation. The LAN8700 device is installed on the EVB board and all associated circuitry is included, along with all config-

uration options.

The Benefits of adding an external MII interface are:

• Easier system and software development

• Verify MAC to PHY interface

• Support testing of FPGA implementations of MAC

• Assist interoperability test of various networks

• Verify MII compliance

• Verify performance of HP AutoMDIX feature

• Verify Variable IO compliance
