CC1352P: Disabling Internal Load Capacitors using SmartRF Studio

Chander G

Part Number: CC1352P

Hi,

We are seeing some emissions at N X 48MHz frequencies. I understand that this may be due to the internal load capacitors of the 48MHz crystal. I wanted to know how we can disable the internal load capacitors using SmartRF studio.

Regards,

Chander

OK. Actually we tried this. But we didn't see any difference in spurious emission. That's why I posted this to double check whether unclicking this checkbox really disables the internal capacitor.

Regards,

If you look at the help text (The question mark next to the tick box) this should be ticked and you should ensure that the value is set to a minimum.
