Hello, @lukaszadrapa
Our company is using your FS32K144HFT0MLHT MCU.
The waveform is abnormal when using an 8MHz passive crystal oscillator (AV08000009). Is this waveform acceptable for your company's MCU?
Will it affect the normal operation of the MCU?
Hi @Kyp
The oscilloscope screenshot does not appear to show the actual 8 MHz crystal waveform. The displayed frequency (~256 Hz) is inconsistent with the expected oscillator frequency and is most likely caused by aliasing due to the selected oscilloscope timebase and sampling rate. Therefore, it is not possible to assess the crystal oscillator quality from this measurement alone. A significantly faster timebase should be used to observe the actual oscillator waveform.
Regards,
Lukas
HI, lukaszadrapa
We apologize, we retested the waveform, and the image is as follows.
Please analyze this and offer any suggestions.
