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

The LA78040 is a vertical deflection output IC for high image quality TV and CRT displays that supports the use of a bus control system signal-processing IC. The sawtooth waveform from the bus control system signal-processing IC can directly drive the deflection yoke (including the DC component). Color TV vertical deflection system adjustment functions can be controlled over a bus system by connecting the LA78040 to a Sanyo LA768X series or LA769XX series bus control system signal-processing IC.
