Description
Ys(YCbCr)
A fast switch for selecting Y/Cb/Cr2 in (or fast
blanking for scart R/G/B in).
Forced Y/Cb/Cr (or scart R/G/B in)
0.7V -----------------
Selecting by IICBUS
0V -----------------
nc;
Y/CVBS1 IN
An alternative input terminal for;
-
Y + Sync signals of Y/C
-
Or CVBS_1
Those two are selected by IICBUS
This terminal is clamped by charging /
discharging the coupling capacitors. It is
recommended that input impedance is kept at
or below 100
Ω
. Input level 1Vp-p/140IRE
DC RESTOR;
A terminal to be connected with a capacitor to
detect the average picture level for DC
restoration. The ratio of the DC restoration is
set by bus.Leave this terminal open if the DC
restoration is not required. ;
nc;
nc;
De
Emphasis
Mon
OUT;
A terminal to De-Emphasis Audio signal, and
pick up detected Audio signal. Connect
capacitor (4700pF) to GND. The time constant
50/75us is set by the IICBUS control “SIF
Freq”. Remove the capacitor for connecting
US/JPN sound multiplex system.
DAC 3;
A terminal to be output High/ Low status by an
open collector interface. The pull up resistance
should be fixed as a sink current is 1mA or less
and the voltage is less than the voltage of IF
Vcc.
IF Vcc(9V);
A Vcc terminal for Y/C circuit. Supply 9V.;
IF DET OUT;
Detected PIF output terminal.(typical output
level 2.2Vp-p)

Description
LOOP F
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.
An input terminal for 2’nd SIF signal and H.
curve correction.
IF VCC
(5V)
A Vcc terminal for the IF circuit. Supply 5V.;
1st SIF IN(1);
1st SIF 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);
IF 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.
