Hi
Reading from icm 20948 datasheet, in low noise mode the max. sampling rate of icm20948 of accelerometer (acc) and gyroscope (gyro) is 1125Hz (ignoring the small difference between acc and gyro). The data output rate (ODR) is calculated by the equation 1125/(1+divisor). With a divisor value of 19, the ODR is around 56Hz.
When the divisor of 19 is applied, does it mean the sampling rate is reduced to 56Hz? If not, is the sampling rate maintained at 1125Hz internally? Is there any algorithum onchip to take average as an first-in-last-out buffer or anything alike?

Hello,
Gyro sample rate divider divides the internal sample rate to generate the sample rate that controls sensor data output rate, FIFO sample rate, and DMP sequence rate. Could you please elaborate on about the algorithm functionality you mentioned?
