SIF input
The input impedance is about 1 k
.
Since interference signals
*
entering this input can
result in buzzing and beat signals, the pattern layout
for the signal input to this pin must be designed
carefully.
*
: Signals that can interfere with audio include video
and chrominance signals. Thus the VIF carrier
signal can cause interference.

The FM detector signal-to-noise ratio can be improved
by inserting a filter in the FM detector bias line.
C1 must be 0.47 μF or higher, and we recommend
1 μF.
If the FM detector is not used, a 2 k
resistor must be
inserted between pin 2 and ground. This stops the FM
detector VCO circuit.
