2.
This range for the servo path is designed to be larger than for the data path so that the servo path can handle
out-of-focus situations.

Input impedance depends on gain setting. Highest gain has lowest input impedance.
Noise figures depend on gain and filter settings, examples given here.

12. Channel pair matching is defined in % of full scale (FS) output at half of the full scale level.
Integral range for G

from minimum to maximum gain is 13 dB (typical).
At the transition BWRF = 63 to 64 the
f may be between
0.2 and +1.7 MHz
