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.
