ADVANCED COMMUNICATIONS & SENSING
In FSK Mode, the default filter setting (“A3” at address $16) is kept, leading to Fc=96 kHz typ.
In OOK Mode, “F3” is set at address $16, leading to (Fc-Fo)=95 kHz typ.
The above ensures that the channel filter is wide enough, therefore characterizing the demodulator response,
and NOT the filter response.
