TA1276AN
TENTATIVE TOSHIBA BIPOLAR LINEAR INTEGRATED CIRCUIT SILICON MONOLITHIC
TA1276AN
PAL / NTSC VIDEO CHROMA AND DEFLECTION IC FOR CTV
(NORMAL SCAN / DOUBLE SCAN MODE)
TA1276AN 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 56pin
dual-in-line shrink-type plastic package.
TA1276AN 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 / 60Hz
auto-detection circuit in Sync. PAL demodulation circuit includes
Baseband signal processing system. And this demodulation
circuit does not required any adjustment.
TA1276AN includes I2C bus interface, so you can adjust various
functions and controls via the bus.
Weight: 5.55g (Typ.)

FUNCTION
1 fsc output
Outputs oscillation waveform of
VCXO.
When 3.58NTSC killer-off this pin
voltage sets 3.2V.
When B / W or other systems
killer-off, this pin voltage sets 1.4V.
Outputs SCP (Sand Castle Pulse).
The output signal consists of clamp
2 SCP output pulse, horizontal blanking pulse, and
vertical blanking.
The minimum load resistance is 3k.
