Power
The CIMaX has 6 power pairs (VCC – GND):
The core power pair must be connected to a 3.3V power source.
The other pairs can be either connected to a 3.3V or 5V power source depending on the voltage
required by the device connected to it.
The DVB1 and DVB2 pairs must be connected to the same power source.
