Function
FM/AM Prescale
bit [15:8] 00
For all FM modes except satellite FM and AM-mode, the combinations of pres-
cale value and FM deviation listed below lead to internal full scale.

recommendation for SIF input levels from
0.1 V
(Due to the AGC being switched on, the AM-output level
remains stable and independent of the actual SIF-level in
the mentioned input range)
