See the DATA_RATE description in RADIO_CFG_0 (see Table 62).
Description
The binary level 2FSK/GFSK/MSK/GMSK frequency deviation in hertz (defined
as the frequency difference between carrier frequency and 1/0 tones) is set
according to Frequency Deviation (Hz) = FREQ_DEVIATION[11:0] × 100.
Description
The DISCRIM_BW value sets the bandwidth of the correlator demodulator. See
the 2FSK/GFSK/MSK/GMSK Demodulation section for the steps required to set
the DISCRIM_BW value.
Description
For optimum performance, the post-demodulator filter bandwidth should be
set close to 0.75 times the data rate. The actual bandwidth of the post-
demodulator filter is given by Post-Demodulator Filter Bandwidth (kHz) =
POST_DEMOD_BW × 2. The range of POST_DEMOD_BW is 1 to 255.
Description
Set to zero.
Description
If SYNTH_LUT_CONTROL (Address 0x113, Table 69) = 0 or 2, set
SYNTH_LUT_CONFIG_0 = 0. If SYNTH_LUT_CONTROL = 1 or 3, this setting
allows the receiver PLL loop bandwidth to be changed to optimize the receiver
local oscillator phase noise.
The DISCRIM_PHASE value sets the phase of the correlator demodulator. See
the 2FSK/GFSK/MSK/GMSK Demodulation section for the steps required to set
the DISCRIM_PHASE value.
