Hi All,
How can I set the ODR of the ADXL355 to 100Hz by using an external clock?
One of ways to get 100Hz is below. Is it correct?
- EXT_SYNC=01
- External clock=3200MHz
- ODR_LPF=0101b

Thank you for your post.
Can you verify that you meant to reference 3200MHz?
Hi NevadaMark,
Sorry, I corrected the settings as follows to get 100Hz ODR.
- Register "0x2B" = "0x05"
- INT2 = External Clock **4x64x100Hz=25.6kHz
If any settings are needed, please let me know.

Hi Kazu,
External clock must be 1.024 MHz, regardless of the ODR you select. Sorry for the confusion. All internal clocks require this rate of an external clock, the device will divide down the clock appropriately based on your settings assuming (and requiring) the external clock be 1.024 MHz.
Hi
How can I get the ODR of 100Hz by using 1.024MHz external clock?

The datasheet say otherwise: an external source provides an external clock at a frequency of 4 × 64 × ODR.
What is the correct statement?
Hi, Did you find out how to implement?
Were you able to change ODR of ADXL355?
