Crystal generating 32 MHz not precisely

Avatar
On my own board I tryed different marks of crystals, whith different capasitors 3...47pf, in different combinations. SX1276 forms radio frequencies with big error, about 0.1-0.3 MHz.
Can you tell me the mark of crystal that works properly with additional capasitors 12pf and dirty board (with soldering flux)?
When I use TCXO, everything is fine.
Register 0x4B in SX1276 is configured for crystal (0x00).

Hello,

a list of XTALs is supplied in AN1200.14, and some references are also in the reference designs themselves. A couple of pF off should offset you at most of 10s of kHz, not more.

thanks

Using crystal 7M-32.000MEEQ-T.
12pf on one side and 18pf on other side gives offset ~20kHz on radio frequency, vice 12pf+12pf.
Is this normal?

... so 12 and 18pF give + (or minus?) kHz ???
and please confirm the offset with 12 and 12pF.

but 20 kHz doesn't sound unreasonnable

Join procedure in case of 12pf+12pf.
My join request is moved to the right.
The offset is not changing, it is stable.
