Attention must be paid to the harmonics of the CLK_OUT output signal f
harmonics produced by an microprocessor clocked with it, since these harmonics can disturb
the reception of signals if they get to the RF input. If the CLK_OUT signal is used, it must be
carefully laid out on the application PCB. The supply voltage of the microcontroller must also be
carefully blocked.
