PAL
/
NTSC Video Chroma And Deflection IC For CTV
(normal scan/double scan mode)
TA1276AFG provides Video, Chroma and Deflection (sync, when double scan mode) circuit for a PAL/NTSC Color
TV, and suitable for a high picture quality, large screen size, wide
and/or double scanning TV. These functions are integrated in a 80
pin QPF plastic package.
TA1276AFG provides a high-performance video processor in
which a YUV double scanning signal can be applied in Video,
PAL/NTSC auto-detection circuit in Chroma and 50/60 Hz
auto-detection circuit in Sync. PAL demodulation circuit includes
Baseband signal processing system. And this demodulation
circuit does not required any adjustment.
TA1276AFG includes I
2
C bus interface, so you can adjust
various functions and controls via the bus.

Data Receive Format
At the moment of the first acknowledge, the master transmitter becomes a master receiver and the slave
receiver becomes a slave transmitter. This acknowledge is still generated by the slave.
The STOP condition is generated by the master.
Optional Data Transmit Format: Automatic Increment Mode
In this transmission method, data is set on automatically incremented sub-address from the specified
sub-address.

Pin 41 H-out (mode SW)
You can select the Double Scan Mode (external CP (clamping pulse) input mode), by connecting Pin 41 to
DEF V
CC
. (the threshold of pin 23: 8.7 V = DEF V
CC
- 0.3 V)
When Double Scan Mode, function of Pin 38 and 40 are changed.
Normal Scan (internal CP) Mode: Pin 41 H-out
The function of Pin 40 is curve correction input, that of Pin 38 is FBP (flay back pulse) input.
The input signals of Y
2
, U/I and V/I inputs (pin 1, 2 and 3), Analog OSD inputs (pin 18, 19 and 20),
Analog RGB inputs (pin 22, 24 and 25) are clamped of the internal CP based on the Y
1
/Sync input (pin
52).
Double Scan (external CP input) Mode: Pin 41 H-out
The function of Pin 40 is EXT/BPP (Note 2) input, that of Pin 38 is H/V BLK (blanking) input.
The input signals of Y
2
, U/I and V/I inputs (pin 1, 78 and 80), Analog OSD inputs (pin 18, 19 and 20),
Analog RGB inputs (pin 22, 24 and 25) are clamped of the external CP based on Pin 40.
In case of Double Scan Mode, bus "V-BLK" should be set (1); OFF.

2) For testing, see the picture sharpness AC characteristics testing circuit diagram. After using the preset values to
transmit the BUS control data, set ACB operation switching to ACB off (01).

1) Set the BUS control data to the preset value.
2) Connect pin 78 to an external power supply (PS) and observe pin 2.
3) Turn the Y mute off (1), turn the black stretch gain off (1), and set the black detect level to 0 IRE (1).
4) Increase the PS voltage from 5 V and measure the DC differential VB of pin 3 where the picture period (high period) of
pin 2 goes low.
5) Set the black detect level to 3 IRE (0).
6) As in 4), measure the DC differential VB3 of pin 3.

Vertical Pull-In Range (1)
Input a 50 Hz composite video signal to pin TP52, vary the vertical frequency of this signal in 0.5H-steps,
and measure the vertical pull-in range.

of subaddress (17) to (001), vary the vertical frequency of a 60 Hz composite video signal
input to pin TP52 in 0.5H-steps, and measure the vertical pull-in range.
Vertical Pull-In Range (3)
Input a 50 Hz composite video signal to pin TP52, vary the vertical frequency of this signal in 0.5H-steps,
and measure the number of Hs when D
2
of the 1

byte changes from 0 to 1 in bus read mode. Also check
that D

byte is 0 when 1 V
=
312.5H, when D
1
is 1 in bus read mode, and 1 V
<
