Block diagrams of the gyroscope filters

In the LSM6DSV320X, the gyroscope filtering chain depends on the mode configuration:

•

Mode 1 (for user interface (UI) and electronic image stabilization (EIS) functionality through the primary

interface) and mode 2

1. When the gyroscope OIS or EIS chain is enabled, the LPF1 filter is not available in the gyroscope UI chain. It

is recommended to avoid using the LPF1 filter in the gyroscope UI chain when the gyroscope OIS or EIS is

used.

2. The LPF1 filter is available in high-performance mode only. If the gyroscope is configured in low-power mode,

the LPF1 filter is bypassed.

In this configuration, the gyroscope ODR is selectable from 7.5 Hz up to 7.68 kHz. A low-pass filter (LPF1) is

available, for more details about the filter characteristics see Table 66. Gyroscope LPF1 + LPF2 bandwidth

selection.

The digital LPF2 filter's cutoff frequency depends on the selected gyroscope ODR, as indicated in the following

table.
