interfaces, connectors, jumpers, and LEDs.
2.1 Usage Setup and Configuration
Power for the TLK110CUSEVM is supplied via a MII connector.
• If 5V is supplied, the on-board voltage regulator, U1, will convert 5V to 3.3V for the device.
• If 3.3V is supplied from the MII connector, R59 should be assembled and R56 should be removed.
• Make sure the J2 jumper is installed in order to supply 3.3V to the magnetic CT.
• Make sure J1 jumper is installed and configured to MII or RMII.
2.2 Address Settings
The PMD address TLK110CUSEVM Physical Layer device is set by the following jumpers:
• J7: PHY ID [0]
• J6: PHY ID [1]
• J5: PHY ID [2]
The default board setting for the PHY address is 01h. The board may be set to any PHY address 00h -
07h by adding jumpers J5 - J7.
