TA1276AFG
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 I²C bus interface, so you can adjust
various functions and controls via the bus.
