10.2. Decoupling
Correct functionality requires de-coupling of the internal power supply voltage (VDEC1/2). Capacitors of 1μF
(recommended value) shall be placed as close as possible to IC pins and shall be connected to ground with the
shortest possible traces. Avoid long lines. It is recommended to insert additional 100 nF capacitors as close as
possible at each VDD pin to ground.

Blocking is required if an antenna with a DC path to ground is used.
Serial capacitance must be < 30 pF.

Parasitic capacitance of the IC pins must be considered as additional
parallel capacitance to the crystal.

Comments on RF Input/Output and Crystal Pins
10.4. RF Pins
A differential RF input provides common-mode rejection to suppress the switching noise of the internal digital signal
processing blocks. At the board-level, the differential RF layout ensures the receiver sensitivity by rejecting any
spurious signals originating from other digital ICs such as the micro-controller.
The RF port is designed for a 100
differential load. A differential DC path between the RF pins is allowed. A DC
path to ground or supply voltage is not allowed and requires capacitive coupling as indicated in Table 10-2.
