SX127x optimization required for different than 32 MHz frequency clock source?

Semtech Transceivers

Hello all,

Given the price of 32MHz TCXO’s, I’ve tested some SX127x chips with clock sources different than 32 MHz frequency and all seems to work fine with no range degradation.

I was wondering if any register optimization might be required given the different clock source frequency.

If I can ask it differently, does the actual Bandwidth depend on the nominal crystal frequency and if it does, then how is it being derived?
