4.11.2

External Reference Supply

To drive/operate the LGA DevKit's interfaces at certain voltage levels, an external reference
voltage may be connected. By default, i.e., without an external reference voltage connected,
the interface operates at 3V to meet the DSB75/DSB-Mini requirements. But if it is required to
operate the interface at another voltage, an external source in the range between 1.2V...5V can
be connected to "REF IN" and "GND" as shown in

Figure 12:

External reference supply and pin header for free level shifter

Please note that this jumper should not be set when the LGA DevKit is connected to a DSB.
