Function
Equivalent circuit
1
SIF INPUT
SIF input. The input impedance is about 1k
. 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 interface
with the audio signal. Also, the VIF carrier signal can
also cause interference.
2
FM BIAS FILTER
FM detector bias line filter input. Used to improve the
FM detector signal-to-noise ratio.
C1 should be at least 0.47
μ
F, and 1
μ
F is
recommended. If the FM detector is not used,
connect pin 2 to ground through a 2k
resister. This
stops the FM detector VCO.
3
SIF CARRIER OUTPUT
SIF carrier output. A 200
resister is inserted in
series with an emitter-follower output.
4
8
VCC
Use the shortest distance possible when decoupling
Capacitors VCC and ground.
Equalizer circuit. This circuit is used to correct the
video signal frequency characteristics.
Pin 9 is the EQ amplifier input
