The calibrated timestamp is calculated from the nominal value using the
formula:
ts_gain[ns] ≈ ts_sensitivity - (ts_trim_coeff * val) / 1000.
The values of ts_sensitivity and ts_trim_coeff are not the same for all
devices, so it is necessary to differentiate them based on the part name.
For the correct values please consult the relevant AN.
