Don't quite understand the question, the screenshot you attached does show how the X1 connects to the WIFI chip, may you elaborate your question a little bit more?
okay, let me clear more, due to someone tell me Laird module need an external 32.768Khz crystal for better performance
so I want check how to connect a external crystal for the Laird EWB module.
Laird EVB schematic just have the picture and BOM list (X1: EPSON FC-135) ,
and update I know the schematic say only connection to external cystal,
but on our customization board, 10pcs only 7pcs workable, 3 pcs failed not start up when connected external 32.768KHz
STM32 have an application note about crystal ( https://www.st.com/resource/en/application_note/cd00221665-oscillator-design-guide-for-stm8afals-stm32-mcus-and-mpus-stm…
but Laird EWB is SIP module, we need more information for How aboutc apply an external 32.768KHz crystal
