ADV7171WBSZ-REEL

Overview

The ADV7171WBSZ-REEL is a digital PAL/NTSC video encoder manufactured by Analog Devices Inc. It converts digital CCIR-601 4:2:2 component video data into analog baseband television signals. The device features four 10-bit DACs, an integrated SSAF™ filter, and advanced power management. It operates on a single 3.3 V or 5 V supply within an industrial temperature range of −40°C to +85°C. Key specifications include an 80 dB video SNR, a 27 MHz clock requirement, and support for multiple output formats including composite, S-Video, YUV, and RGB via a 44-lead MQFP package.

Feature Summary

• Supports simultaneous multi-format video outputs including composite, S-Video, YUV, and RGB.
• Integrates Super Sub-Alias Filter (SSAF) for high-quality luminance processing.
• Includes programmable luma and chroma filters with extended frequency response options.
• Features complete on-chip timing generation and master/slave operation 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 'WBSZ-REEL' against the manufacturer's current ordering guide to confirm package type and reel quantity. Ensure the design supports the required 27 MHz clock input and appropriate RSET resistor values for the selected supply voltage. Confirm that the MQFP-44 footprint matches the PCB layout requirements.

Selection Notes

Select this model when a digital-to-analog conversion for standard definition video is required. Compare with the ADV7170 if Macrovision® AntiTaping functionality is needed, as it is exclusive to that variant. Ensure the system can accommodate the 44-lead MQFP package dimensions and thermal dissipation characteristics specified in the datasheet.

Part Context

This component belongs to the ADV7170/ADV7171 family of integrated digital video encoders. It is designed to replace older discrete encoding solutions by integrating multiple video processing functions onto a single chip. The part is commonly used in multimedia applications requiring reliable conversion from digital component inputs to analog broadcast standards.

Replacement Considerations

The ADV7170 is a compatible alternative within the same family but includes Macrovision® AntiTaping Rev. 7.1 support. Verify pin compatibility and register settings when substituting between these variants to ensure correct video output configuration.
