Hello, I'm using the FRDM-MCXA153 Eval Kit and I would like to know the purpose of the Y1 Crystal. I see that it is an 8Mhz crystal but it is not populated. Do I need to add that part on the board?
Thank you
AN14798 System Oscillator Usage for MCX A series
Frequency is the main parameter for selecting the crystal. For MCX A series MCU, 8 MHz~50 MHz are supported
Y1 is the reserved footprint for the external 8 MHz crystal on the MCX A153. It is not populated by default on the FRDM-MCXA153 production board. Unless you specifically need to enable an external crystal clock source, there is no need to install it.
Thank you.
