the vicinity of the MEMS device, we recommend the customer to test on the PCB with a vibrometer to confirm that the MEMS
device is not being excited by any resonance frequency.
The recommendation is to place any acceleration or vibration sources as far away as possible from MEMS devices. However, in the
situation that the customer has limited board space and placement options are limited, the recommended distance is ≥5mm away
from the MEMS device. If placement is uncertain, customer should consult with local FAE to provide a more detailed analysis.
