... Ethernet applications. The LAN8187 requires only a single +3.3v supply, and has an integrated +1.8v supply to run the core digital logic. The EVB8187 is a customer evaluation board that interfaces a standard 40 pin MII connector from an existing MAC controller to the SMSC LAN8187 Ethernet PHY, and out to an RJ-45 Ethernet Jack for 10/100 connectivity ...

... AutoMDIX options The LAN8187 supports AutoMDIX on the analog output pins. The EVB8187 supports the option to disable AutoMDIX and to manually select the channel. Jumper J3 is used to manually disable AutoMDIX funcion. Placing a jumper accross J3 will disable AutoMDIX functionality and prevent the automatic switching of the TX* with RX*. Please refer to the LAN8187 datasheet for more information on AutoMDIX function ...
