The alignment of the LC-discriminator circuit should be
done with little or no effect on the AFC function. This can
be realized by:
–
switching Pin 21 to open-circuit
–
connecting Pin 1 to a voltage source of 2 V
–
using a low signal level for alignment.
In general, ceramic discriminator devices can be used,
too. In this case, the effect of unavoidable spreads in the
frequency characteristics of these case ceramic devices in
conjunction with the IC characteristic has to be consid-
ered. For example, mismatches of the characteristics
between selectivity block and FM discriminator will lead
to an increased signal-to-noise ratio at low signal level as
well as to a higher demodulation distortion level or to an
asymmetrical AFC.
