Description :

VIDEO, CHROMA AND SYNCHRONIZING SIGNALS PROCESSING IC FOR PAL / NTSC / SECAM SYSTEM COLOR TV

TB1226EN 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 56-pin shrink DIP plastic package. TB1226EN 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 / 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.

Video section

1. Built-in trap filter
2. Black expansion circuit
3. Variable DC regeneration rate
4. Y delay line
5. Sharpness control by aperture control
6. γ correction

Chroma section

1. Built-in 1H Delay circuit
2. PAL / SECAM base band demodulation system
3. One crystal color demodulation circuit (4.43MHz, 3.58MHz, M / N-PAL)
4. Automatic system discrimination, system forced mode
5. 1H delay line also serves as comb filter in NTSC demodulation
6. Built-in band-pass filter, SECAM bell filter
7. Color limiter circuit
