Description
Equivalent circuit
1
SIF INPUT
SIF input. The input impedance is about 1 k
. Since
buzzing and buzz beating can occur if interference enters
this input pin, care must be taken when design the pattern
layout for this pin. Note that the video and chrominance
signals are especially likely to interfere with the audio
signal. Also, the VIF carrier signal can also cause
interference.

2
FM power supply filter
FM detector bias line filter input. Used to improve the FM
detector signal-to-noise ratio.
C1 should be at least 0.47 μF, and 1 μF is recommended.
If the FM detector is not used, connect pin 2 to ground
through a 2-k
resistor. This stops the FM detector VCO.

SIF converter
Pin 3 is the SIF converter output. The signal is passed
through a 6-MHz bandpass filter and input to the SIF
circuit.
