REGISTER 6—CORRELATOR/DEMODULATOR REGISTER
Register 6—Correlator/Demodulator Register Comments
• See the FSK Correlator/Demodulator section for an example of how to determine register settings.
• Nonadherence to correlator programming guidelines results in poor sensitivity.
• The filter clock is used to calibrate the LP filter. The filter clock divide ratio should be adjusted so that the frequency is 50 kHz.
• The filter should be calibrated only when the crystal oscillator is settled. The filter calibration is initiated every time Bit R6_DB19
• Discriminator_BW = DEMOD_CLK/(4 × DEVIATION_Frequency). See the FSK Correlator/Demodulator section.
• When LNA Mode = 1 (reduced gain mode), the Rx is prevented from selecting the highest LNA gain setting. This can be used when
The formula is XTAL/FILTER_CLOCK_DIVIDE.
is set high.

linearity is a concern. See the Readback Format section for details of the different Rx modes.
