LAN9500 CEB with MII Interface
The LAN9500 CEB with MII interface provides the same functionality as the LAN9500 CEB (non-MII)
with additional features. The LAN9500 CEB with MII interface provides a user accessible MII interface
for connection to an external PHY and a JTAG debugging interface. The provided jumpers allow for
additional configuration of the device, including the option to set the device to bus-powered or self-
powered mode.

MII interface. A dashed line “---” shown in the “Position” column indicates the board’s default jumper
setting. These settings may be changed as needed. However, any deviation from the default settings
must be approached with care and knowledge of the board. An incorrect jumper setting may disable
the board.

details the various jumper settings available on the LAN9500 customer evaluation board with
When an external PHY is connected to the MII port of the LAN9500, the LAN9500 CEB
must be configured for external PHY operation.
JP5 and JP7 must always be connected in the same positions (i.e. 1-2 and 1-2, or 2-3 and
2-3 only).
