RFFC2071/2072
Note 1: An RC low pass filter could be used on this line to reduce digital noise.
Note 2: If the device is under software control this input can be configured as a general purpose output (GPO).
Note 3: Connect a 51kΩ resistor from this pin to ground, this pin is sensitive to low frequency noise injection.
Note 4: DC voltage should not be applied to this pin. Use either an AC-coupling capacitor as part of lumped element matching
network or a transformer (see evaluation board schematic).
Note 5: This pin must be connected to ANA_VDD2 using an RF choke or a transformer (see application schematic).
