Pin
Function
Equivalent circuit
SIF input
The input impedance is about 1 k
. The pattern layout for
the input circuit for this pin must be designed carefully, since
buzzing and/or beating can be caused by interference
signals. Video signals, the chrominance signal, and the VIF
carrier signal can cause interference in the audio signal.
1
SIF INPUT
The FM detector signal-to-noise ratio can be improved by
inserting a filter in the FM detector bias line.
C1 must be at least 0.47 F, and 1 F is recommended.
If the FM detector is not used, insert a 2-k
resistor between
pin 2 and ground. This stops the FM detector VCO.
2
FM power supply filter
Pin 3 is the first SIF output.
This is the output pin for the audio carrier to which P/S
separate detection has been applied. This is an emitter-
follower output with a 200
series resistor inserted.
3
First SIF output
