Stm32wl33 with tcxo

WWang.15 · ‎2025-04-02

Dear ST experts

If we want to use tcxo on stm32wl33, should we choose 1.8v or 3v3 power domain for the vcc of this tcxo?

You can use TCXO. At this stage we have only 1 reference design with TCXO (4-Layer Reference design based on SMDs with STM32WL3 QFN48 SoC - 169 MHz - 27 dBm).

Usually, we used to supply it at VDD level (you can check the schematic).

Best Regards.
