See the FSK Correlator/Demodulator section for an example of how to determine register settings.
Nonadherence to correlator programming guidelines results in poorer sensitivity.
The filter clock is used to calibrate the IF filter. The filter clock divide ratio should be adjusted so that the frequency is 50 kHz.
The formula is XTAL/FILTER_CLOCK_DIVIDE.
The filter should be calibrated only when the crystal oscillator is settled. The filter calibration is initiated every time Bit R6_DB19
is set high.
Discriminator_BW = ( DEMOD_CLK × K )/(800 × 10
When LNA Mode = 1 (reduced gain mode), the Rx is prevented from selecting the highest LNA gain setting. This can be used when
linearity is a concern. See Table 5 for details of the different Rx modes.
