TB1230AN Datasheet – Signals Processing IC

The TB1230AN is a Video, Chroma and synchronizing Signals Processing IC made by Toshiba, supplied in a DIP 56 Pin Type package. The absolute maximum ratings table on this page lists the 7 limits from the manufacturer's datasheet that must not be exceeded. This page brings together the TB1230AN maximum ratings, with the full datasheet PDF to preview below or download.

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
