TOSHIBA Bi-CMOS INTEGRATED CIRCUIT
SILICON MONOLITHIC
TB1230AN
VIDEO,CHROMA AND SYNCHRONIZING SIGNALS PROCESSING IC FOR PAL / NTSC
SYSTEM COLOR TV
TB1230AN that is a signal processing IC for the PAL / NTSC
color TV system integrates video, chroma and synchronizing
signal processing circuits together in a 56-pin shrink DIP plastic
package.
TB1230AN incorporates a high performance picture quality
compensation circuit in the video section, an automatic PAL /
NTSC discrimination circuit in the chroma section, and an
automatic 50 / 60Hz discrimination circuit in the synchronizing
section. Besides a crystal oscillator that internally generates
4.43MHz, 3.58MHz and M / N-PAL clock signals for color
demodulation, there is a horizontal PLL circuit built in the IC.
The PAL demodulation circuit which is an adjustment-free circuit
incorporates a 1H DL circuit inside for operating the base band
signal processing system.
Also, TB1230AN makes it possible to set or control various functions through the built-in I2C bus line.
