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.
