Monolithic Linear IC
LA7615
Single-Chip NTSC Color TV IC
Overview
The LA7615 is an NTSC color TV IC that supports
computer control over an I2C bus. In addition to improved
quality and increased functionality in color TV products,
this IC supports the development of a TV set product line
in software and the simplification of end product design.
The provision of an I2C bus means that this product can
also respond to desires for increased total manufacturing
productivity, including improved automation of computer
controlled production lines.
Functions
• I2C bus control, VIF, SIF, Y, C, and deflection circuits
integrated on a single chip.
Features
• Pursuit of higher integration levels
The LA7615 integrates VIF, SIF, luminance,
chrominance, and deflection (horizontal and vertical
synchronization) circuits, A/V switching, and power
supply control on a single chip.
• Bus control for reduced external component counts and
mechanical adjustment points
All the LA7615 signal-processing circuits can be
controlled and adjusted digitally over the I2C bus. All
adjustments, both those required during manufacture and
the user controls, can be controlled over the I2C bus, and
both function selection and characteristics settings can
be performed in software over the I2C bus. This
increases flexibility in designing a product line of TV
sets and also enhances productivity by allowing mixed
production runs.
While this device supports multifunction and good
performance, it is also economical in that it achieves
reduced power and reduced pin count.
