Description :

LA76810 is a VIF/SIF/Y/Deflection 1chip IC for PAL/NTSC color television sets.

As generation after generation of color TV signal-processing IC is developed, and as rationalization progresses in the design of these ICs, the companies that produce these ICs find themselves in a battle not just for market share, but for their very survival. TV manufacturers, who are facing the rapid collapse of prices in consumer products, now strongly desire both support for global products and reduced total costs in the ICs for these products. To respond to these needs, Sanyo has developed the LA76810 Series of single-chip color TV signal-processing ICs.

Features for LA76810

1. Global Product Support (Pin to Pin Structure)

There are now three formats used for color TV broadcasts: PAL, NTSC, and SECAM. Since the signal processing required for these formats differs, it has been necessary to design printed circuit boards using different ICs for these different signal formats. However, since the LA76810 Series ICs are formed with a pin to pin structure as the pin arrangement, these products allow sharing of the printed circuit board circuit constants and layout, the items that make up the customer’s design know-how.

(1) LA76810: Multi-format support (PAL, NTSC, and SECAM)
(2) LA76812: PAL and NTSC support

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
