TA1270BF
PAL / NTSC VIDEO CHROMA AND SYNC PROCESSING SYSTEM FOR PIP / POP / PAP
TA1270BF is a PAL / NTSC color TV signal processor IC suitable for PIP / POP / PAP. The IC integrates video, chroma and sync processor circuits. It comes in a 48pin flat package. The video block uses a chroma trap, the chroma block a PAL / NTSC automatic identifier circuit, and the sync processor block a 50 / 60 Hz automatic identifier circuit. The PAL demodulator circuit contains a baseband signal processor, making the circuit adjustment free. The TA1270BF incorporates an I2C bus, enabling control to be set via the bus line.
