RECOMMENDATIONS FOR FSK MODULATION
XTAL1, CFSK pins.
Recommendation
: a R_off resistor can be added in parallel with the FSK switch to optimize the transient
response of demodulated signal. Table 6 gives the optimized R_off values for two deviations. Note that there is
no footprint for R_off resistor on the layout figure 15. When used, this component can be soldered on top of C3.
