Dual SX1280 shared XTAL

Semtech Transceivers SX128x family
#1

Is it possible to share the 52MHz XTAL in a dual SX1280 setup?
i.e. XTAL connected to XTA/XTB on one SX1280 and connect XTB from #1 to XTA on #2 or any other configuration that would work.

Any info on this? Same question

Yep, we made that. One TCXO on two SX1280. But TCXO is of course different with XTAL.

I mean with a regular crystal, not a TCXO. I know that some MCUs support sharing the crystal between them.

We didn’t use a XTAL, so I can’t help
