The problem of MCLK frequency of LIS25BA [Copy link]

 

I would like to ask you, does the MCLK of LIS25BA have to use the frequency of 12.288M? Can it use other frequencies, such as 6.144M, 24.576M? The specification only states that the typical frequency is 12.288M, but does not specify the maximum and minimum frequencies? Does it mean that other frequencies can be used?

The accuracy written below is ±0.1%. Other frequencies should not be used. However, under normal circumstances, if the frequency is not higher than the maximum frequency, the sensor should not be able to distinguish whether the input frequency meets the requirements. Theoretically, it should work. The calculation method may require special processing. You can try it specifically.

This frequency is a bit troublesome.

Ok, I'll try it first, thanks for your guidance.
