AD721JP

Overview

The AD721JP is an RGB to NTSC/PAL encoder manufactured by Analog Devices Inc. It converts red, green, and blue color component signals into corresponding luminance and chrominance signals compliant with NTSC or PAL standards. The device combines these outputs to provide a composite video signal while maintaining separate outputs for S-Video applications. Designed for driving 75 Ω reverse-terminated loads, it eliminates the need for external filters or delay lines. The AD721JP supports logic-selectable encoding modes and includes a bypass mode for direct signal routing.

Feature Summary

• Converts RGB components to NTSC or PAL luminance and chrominance signals
• Provides separate composite, luminance, and chrominance outputs
• Logic-selectable encoding standard and operational modes
• Integrated bypass mode for direct signal amplification

Applications

• RGB to NTSC or PAL encoding systems
• Driving RGB signals into 75 Ω reverse-terminated loads
• Composite video generation in display equipment

Part Context

The AD721 is part of Analog Devices' video encoder family, specifically designed for converting component video signals into broadcast-standard formats. The 'JP' suffix typically denotes a plastic package variant within this series, distinguishing it from ceramic or other package options available in the broader product line.
