Single-Chip Color TV IC Series Developed
IC product series provides support for both low cost and global
products.
LA76810 Series
Overview
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 col-
lapse 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.
To provide reduced design costs in application products, the LA76810 Series are designed to support
end products with common printed circuit boards across the product line, and also to support global
products by supporting a variety of TV standard combinations, including NTSC, PAL/NTSC, and
multi-format. To reduce total costs, these ICs are based on the concept of reducing adjustments in
external components by using an I2C bus, and furthermore aim at reducing the number of adjustments
by adopting adjustment-free technology (e.g., the IF circuit is adjustment free), and by using circuit
technologies (such as S-BPF/TRAP, DDS, and CCD) to reduce the number of components.
Additionally, these products support end product differentiation by the adoption of unique technolo-
gies, such as built-in SG circuits, demodulation ratio and demodulation angle adjustment functions,
and an AKB function.
Features
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.
• LA76810: Multi-format support (PAL, NTSC, and SECAM)
• LA76812: PAL and NTSC support
