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 I 2C 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.
