Block diagrams of the gyroscope filters

In the LSM6DSOX, the gyroscope filtering chain depends on the mode configuration:

•

Mode 1 (for User Interface (UI) and Electronic Image Stabilization (EIS) functionality through primary

interface) and Mode 2

MIPI I3CSM

In this configuration, the gyroscope ODR is selectable from 12.5 Hz up to 6.66 kHz. A low-pass filter (LPF1) is

available if the auxiliary SPI is disabled, for more details about the filter characteristics see Table 67. Gyroscope

LPF1 bandwidth selection.

The digital LPF2 filter cannot be configured by the user and its cutoff frequency depends on the selected

gyroscope ODR, as indicated in the following table.
