ADV7171KSUZ

Overview

The ADV7171KSUZ is a digital PAL/NTSC video encoder manufactured by Analog Devices Inc. It converts CCIR-601 4:2:2 YCrCb data into analog baseband signals using four 10-bit DACs. The device operates on a single 3.3 V or 5 V supply and supports NTSC M, PAL M/N, PAL B/D/G/H/I, and PAL60 standards. It features an integrated super sub-alias filter (SSAF), a 32-bit direct digital synthesizer for color subcarrier generation, and programmable luma/chroma filters. The component utilizes a 44-lead MQFP package and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Converts digital component video data into standard analog composite, S-Video, YUV, and RGB outputs.
• Integrates SSAF technology for extended luminance frequency response and sharp stop band attenuation.
• Supports simultaneous multi-standard video output formats including CVBS, Component, and EuroSCART.
• Includes advanced power management with configurable normal, low power, and sleep modes.

Applications

• High performance DVD playback systems
• Portable video equipment such as digital still cameras and laptop PCs
• Digital satellite and cable set-top boxes

Procurement Notes

Verify the specific suffix 'KSU' against official documentation to confirm the exact package type and temperature grade. Ensure that the required 27 MHz clock signal and appropriate voltage reference components are included in the design. Confirm compatibility with the target system's I2C interface requirements before finalizing procurement.

Selection Notes

Select this component when a high-quality digital-to-analog conversion for broadcast-standard video is required. The device is suitable for applications needing precise color reproduction and support for multiple global television standards. Consider the available output formats and the need for onboard timing generation when evaluating system architecture.

Part Context

This part belongs to the ADV7170/ADV7171 family of integrated digital video encoders. These devices are designed to replace discrete encoding solutions by providing a complete conversion path from digital component inputs to analog TV signals. The family shares core functionality but may differ in specific pinouts or feature sets depending on the suffix.

Replacement Considerations

The ADV7170 is a related model within the same family. Verify functional equivalence regarding supported video standards and output configurations before substitution. Check datasheet specifications for any differences in power consumption or package dimensions.
