The EVB-LAN8700 is a a PHY Evaluation Board (EVB) that interfaces a MAC controller to the SMSC
LAN8700 Ethernet PHY through an MII connector, and out to an RJ-45 Ethernet Jack through industrial
temperature magnetics for 10/100 connectivity.
Schematics(*.pdf and *.dsn), BOM (bill of materials), user guide, gerber files and Layout board file are
all available on the EVB web site link below.

The EVB-LAN8700 is designed to plug into a user's test system using a 40 pin Media Independent
Interface (MII) connector. The MII connector is an AMP 40 pin Right Angle through hole MII connector,
PN AMP- 174218-2. The mating connector is PN AMP 174217-2.
