Operation with AM-IF
Level and stop information (on pins 6, 13, 14, 15 and 16) is provided for the modes FM-MUTE-ON and
FM-MUTE-OFF. This information is also available in the FM-OFF mode when an AM-IF signal is input (for example
455 kHz). This can also provide a valid detuning information when a suitable AM-IF resonance circuit is provided for
demodulator (see Fig.18).
