routed as short as possible and not in proximity of digital I/O signals. This is especially required
for the High Data Rate Modes, refer to
Crosstalk from digital signals on the crystal pins or the RF pins can degrade the system perfor-
mance. Therefore, a low-pass filter (C3, R1) is placed close to the CLKM output pin to reduce
the emission of CLKM signal harmonics. This is not needed if the CLKM pin is not used as a
microcontroller clock source. In that case, the output should be turned off during device
initialization.
The ground plane of the application board should be separated into four independent fragments,
the analog, the digital, the antenna and the XTAL ground plane. The exposed paddle shall act as
the reference point of the individual grounds.
