(*1) When using this device at above Ta=25℃, the power dissipation decreases by 15.9mV per 1℃ rise.
(*2) This IC is weak against static electricity and surge impulse. Please take counter measure to meet, if
necessary.
(*3) This IC is not proofed enough against a strong E-M field by CRT which mau cause function error
and/or poor characteristics. Keeping the distance from CRT to the IC longer than 20cm, or if cannot,
placing shield metal over the IC, is recommended in an application.

Description
LOOP Filter
Filter;
ilter;
A terminal to be connected with loop filter for
PIF PLL. The terminal voltage controls the PIF
VCO frequency.;
DC NF;
A terminal for connecting a capacitor for DC
NF. This filter is very sensitive for the Audio
quality; therefore connect capacitor to a stable
GND point.
In selecting L system, the capacitor works for
PIF AGC filter.
SIF OUT;
An output terminal for a 2’nd SIF signal, which
is mixed down by a regenerated carrier.
IF GND;
The GND terminal for IF circuit.;
SIF IN / H corr.;
corr.;
An input terminal for 2’nd SIF signal and H.
curve correction.
IF VCC (5V);
(5V);
A Vcc terminal for the IF circuit. Supply 5V.;
1’st SIF IN(1);
IN(1);
1’st SIF IN(2);
IN(2);
Input terminals for 1’st SIF signals.
If not using Split input, leave these pins open,
and turn the IICBUS bit of “Spl/ Int” [s0C/d7]
to “1”
Nc ( to GND );
Connect this pin to GND to isolate PIF and
1stSIF input.
RF AGC;
An output terminal for RF AGC. A pull up
resistor is required because of its open collector
output. A de-coupling capacitor should be also
connected to adjust the response.
IF IN(1)
IN(1);
(1);
IF IN(2);
IN(2);
Input terminals for IF signals. Pin 6 and 7 are
the both input poles of a differential amplifier.
The normal input level is 90dB(uV); input
impedance is 1.5 k ohms.

'Relative' mode refers the IF input frequency, which is
tuned by AFT loop.
Set 'Relative' mode in normal receiving, and 'Absolute'
in channel searching. Even setting the 'Relative' mode,

set to L-system as to;
- Turn the modulation polarity to positive
- Delay the AGC time constant (Peek AGC),
with switching the IF AGC filter to the capacitor
of DCNF pin (10uF) instead of IFAGC pin
(0.47uF) .
- SIF AM demodulation (Split carrier only)
with switching the SIF AGC filter to the
capacitor of IFAGC pin (0.47uF) .

READ MODE
! General warning
The read bus flags indicate that a certain signal is
detected at the moment. But reliability of detection
result is not so accurate if checking only one flag, that
confirming several flags, which means similar result
by each other, at the same time is recommended.
