Description
Equivalent circuit
10
Composite video output
Output for the video signal that includes the SIF carrier.
A resistor must be inserted between pin 10 and ground to
acquire adequate drive capability.
R
≥
300
11
12
VCO tank
VCO tank circuit used for video signal detection.
See the coil specifications provided separately for details
on the tank circuit. This VCO is a vector synthesis VCO.
13
AFT OUTPUT
AFT output. The AFT center voltage is generated by an
external bleeder resistor. The AFT gain is increased by
increasing the resistance of this external bleeder resistor.
However, this resistor must not exceed 390 k
.
This circuit includes a control function that controls the AFT
voltage to naturally approach the center voltage during
weak field reception.
14
RF AGC OUTPUT
RF AGC output. This output controls the tuner RF AGC.
A protective 100-
resistor is inserted in series with the
open collector output. Determine the external bleeder
resistor value in accordance with the specifications of the
tuner.
15
1st SIF INPUT
First SIF input. A DC cut capacitor must be used in the
input circuit.
If a SAW filter is used:
The first SIF sensitivity can be increased by inserting an
inductor between the SAW filter and the IC to neutralize the
SAW filter output capacitance and the IC input
capacitance.
When used in an intercarrier system:
This pin (pin 15) may be left open.
