TA1270BFG

PAL / NTSC VIDEO CHROMA AND

SYNC PROCESSING SYSTEM FOR PIP / POP / PAP

TA1270BFG 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 TA1270BFG incorporates an I2C bus, enabling control to be

set via the bus line.
