FM BW (FM bandwidth): must be set in accordance with the application note
“Understanding the Demodulation and Data Slicing Features”, concerning the
relationship between data rate, frequency deviation and demodulator capabilities.
Data Slicer Threshold: the output of the discriminator can be compared to:
Enable PA on Lock Detect: transmission is forbidden until the PLL is locked.
PLL Lock Precision: definition of lock and unlock “diagnosis” (please refer to the
datasheet for more details about this point, default values are valid for many
applications).
Maximum Frequency Deviation (kHz): indicates the maximum frequency deviation
that can be chosen in the SETUP menu.
Operating mode:
Automatic computing of frequencies (TX mode):
– An internal threshold (“internal mode”): “absolute” slicing is possible (no need
– Its own average value (“external mode”): the baseband signal must be DC

software will calculate and display the two closest frequencies (F0 for logical
“0” and F1 for logical “1”) that the AT86RF211 is able to synthesize. “eps [Hz]”
gives you the errors between expected and actual synthesized frequencies.
