Description
Equivalent circuit
No.7939-17/20
LA7567BVA
Video output (including the SIF carrier) pin. A
resistor must be inserted between pin 10 and
ground to acquire the pin circuit's drive capability.
R

Composite video output
Video detector VCO tank circuit connection. See
the coil specifications provided separately for
details on this tank circuit. This is a vector
synthesis VCO circuit.

AFT output
The AFT center voltage is created by an external
bleeder resistor. The AFT gain is increased by
increasing the value of this external bleeder
resistor.
The resistor value must be limited to be no more
than 390
.
This IC includes a function that controls the AFT
voltage to naturally go to the center voltage during
weak field reception.

AFT OUTPUT
RF AGC output
This output controls the tuner RF AGC. A 100
protective resistor is inserted in series with this
open collector output. Determine the value of the
external bleeder resistor by referring to the tuner
specifications.

RF AGC OUTPUT
First SIF input
A capacitor must be used to cut the DC component
of the input to this input circuit.
When a SAW filter is used:
The first SIF sensitivity can also 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.
If this IC is used with an intercarrier, this pin (pin
15) may be left open.
