Table 9. Relationship Between Slew Rate Speed and Settling Time Based on a General Resonant Frequency f0'
Resonance Frequency f0’ (Hz) slew_rate[1:0] Settling Time (ms)
0b00
40 * (100 / f0’)
f0’
0b01
0b10
24 * (100 / f0’)
16 * (100 / f0’)
0b11
12 * (100 / f0’)
Note that the orientation of the camera module can affect the settling time due to the influence of gravity on the barrel.
