Usage Notes
1. AM/FM switching: Pin 31 (IF V
CC
)
This pin is shared with the IF V
CC
. When the FM IF is operated, the IC automatically switches to FM mode. (Note
that the switching reference voltage is 3.3 V.)
Figure 1
2. FM SD and SD adjustment
The FM SD and the IF counter buffer operate with the elements shown below.
The following conditions are required for FM SD operation.
V
30
> V
A
:
The S-meter voltage must be higher than the regulator voltage.
V
23
< 0.7 V (V
BE
): The Hall detector and band mute must not operate.
V
29
= H:
A high level must be applied to pin 29 through a 100 k
resistance.
The following condition is required for IF buffer operation.
V
19
= H:
A high level must be applied to pin 19 through a 51 k
resistance.
