Description
IF AGC;
A terminal should be connected to an IF AGC
filter. Connect 0.47uF of capacitor to
ＧＮＤ
.
In selecting L system, the capacitor works for
1st SIF AGC.
nc;
PIF Filter
;
A terminal to be connected to a filter for
stabilizing the PIF VCO center frequency. Put a
capacitor of 10 uF.
FM
F
ilter
A terminal should be connected to an FM PLL
filter. Put a lag lead CR filter.;
nc;
Xtal (4.43MHz);
A terminal should be connected with a
4.433619MHz crystal oscillator. The oscillated
signal leads to the chroma demodulation, H out
frequency tuning, AFT, etc.;
APC Filter;
A terminal should be connected with an APC
filter for chroma demodulation. This terminal
voltage controls the frequency of VCXO.;
nc;
SECAM Filter;
The terminal should be connected a SECAM
filter for holding SECAN reference frequency.
Connect 0.47uF to GND, If not using
SECAM decoder on TB1261, put at least 0.01uF
of capacitor to GND.
nc;
Y/C VCC;
A Vcc terminal for Y/C circuit. Supply 5V.;
R OUT;
G OUT;
B OUT;
Terminals for R/G/B signal output, should be
lead to CRT driver. Connect resistances to
GND, for the current source if the slew rate is
not enough. Due to the source current
limitation, the resistances should be 2.0k
Ω
or
more.;
nc;
nc;
Y/C GND;
The GND terminal for Y/C circuit.;
VM OUT;
The output terminal for applying veracity
scanning modulation (VSM). The IIC Bus
controls phase and Gain of VSM.;

Description
DAC1;
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 pull up voltage should be less than the
voltage of RGB Vcc.
YS/YM SW;
A terminal for switching of EXT RGB Mode and
fast transparent.
EXT. RGB
2.1V -----------------
Half tone
0.7V -----------------
TV
0V -----------------
EXT. R IN;
EXT. G IN;
EXT. B IN;
Input terminals for EXT R/G/B signals. The
signals are clamped by capacitors, therefore the
input impedance should be low, 100 ohms or
less is recommended. For this input, the
brightness control with ABL is available.
ABL OFF: for small area like OSD
ABL ON: for large area like TELETEXT
(input level 0.7Vp-p/100IRE)
nc;
RGB VCC (9V);
A Vcc terminal for RGB block. Supply 9V.
SCL;
An input terminal for IICBUS clock.;
SDA;
An input/output terminal for IICBUS data.;
EHT IN;
The input terminal for EHT. The ratio of EW /
V is controlled by bus.;
nc;
nc;
ABCL IN;
An input terminal for ABL/ACL control. Control
voltage range is 5.0 - 6.0V. The ratio of ABL
versus ACL can be set by bus control.;
Bed pin;
Connect GND.
The earth pattern should be recommended to be
isolated from Def GND and connect IF GND.
EW OUT;
An output terminal for E-W OUT.
CW OUT;
An output terminal for the continuous chroma
sub-carrier frequency wave, with amplitude of
0.4Vp-p (typ).
