Hello, I have an amplitude problem about crystal 32.768khz of PCA21125:
The oscilloscope shows that the frequency of the crystal signal is 32.76khz.
The peak to peak value of the waveform OSCI is 0.8V, the positive peak reaches 0.5V, and the negative peak reaches -0.3V.
The peak to peak value of the waveform OSCO is 0.4V, the positive peak reaches 0.4V, and the negative peak reaches 0V.
I want to know, is the amplitude of such a wave in the normal range? Can the amplitude of such a crystal signal ensure that PCA21125 works normally?
