The AFC_SCALING_FACTOR can be expressed as
The settings for KI and KP affect the AFC settling time and
AFC accuracy. The allowable range of each parameter is
KI > 6 and KP < 7.
The recommended settings to give optimal AFC
performance are KI = 11 and KP = 4. To trade off between
AFC settling time and AFC accuracy, the KI and KP
parameters can be adjusted from the recommended settings
(staying within the allowable range) such that
AFC Correction Range = MAX_AFC_RANGE × 500 Hz

AFC_SCALING_FACTOR
When the RF_DIVIDE_BY_2 (R1_DB18) is enabled, the
programmed AFC correction range is halved. The user
accounts for this halving by doubling the programmed
MAX_AFC_RANGE value.
Signals that are within the AFC pull-in range but outside
the IF filter bandwidth are attenuated by the IF filter. As a
result, the signal can be below the sensitivity point of the
receiver and, therefore, not detectable by the AFC.
