Hello,For the NX2016SA 32 MHz EXS00A-CS06654, C0 = 0.6pFTo assure no startup problem, for STM32WB, gain margin for HSE > 5 and for LSE > 3Best Regards.

Hi Lukas,The pin PB6 is dedicated to drive the TX/RX for the ext PA.A dedicated application note will be soon available on st.comBest Regards.Marc.

Hi Eugene,The first Ext PA we have designed with the STM32WB55 is the SKY66118_11Your choice is more complex because there 3 possible paths TX/RX/Bypass) ans the possibility to connect 2 antennas.We plan also to evaluate your reference.Best Regards.M...

In the MB1355 schematics what is the purpose of two antenna's? You have one PCB if you want to use the embedded antenna on the board or you have a SMA connector to connect an external antenna if you have your antenna.How to calculate the unfitted ca...

Re: Question about choosing 32MHz HSE quartz crystal

Re: I see that the STM32WB55xx supports a Rf amplifier using Pin PB0 as TX indicator. Is there any provision for a external pre-amplifier RX indicator and sleep mode indicator to drive a external FEM such as the SKY66112? It needs TX,RX and Sleep mode inputs.
