TB1245N
VIDEO, CHROMA AND SYNCHRONIZING SIGNALS PROCESSING IC FOR
PAL / NTSC / SECAM SYSTEM COLOR TV
TB1245N that is a signal processing IC for the PAL / NTSC /
SECAM color TV system integrates video, chroma and
synchronizing signal processing circuits together in a 56pin
shrink DIP plastic package.
TB1245N incorporates a high performance picture quality
compensation circuit in the video section, an automatic PAL /
NTSC / SECAM discrimination circuit in the chroma section, and
an automatic 50 / 60 Hz discrimination circuit in the
synchronizing section. Besides a crystal oscillator that internally
generates 4.43 MHz, 3.58 MHz and M / N-PAL clock signals for
color demodulation, there is a horizontal PLL circuit built in the
IC.
The PAL / SECAM demodulation circuit which is an
adjustment-free circuit incorporates a 1H DL circuit inside for
operating the base band signal processing system.
Also, TB1245N makes it possible to set or control various
functions through the built-in I2C bus line.
