ADV7181CBSTZ-REEL

Overview

The ADV7181CBSTZ-REEL is a multiformat video decoder and RGB graphics digitizer manufactured by Analog Devices Inc. It features four 10-bit ADCs sampling up to 110 MHz and six analog input channels. The device supports NTSC, PAL, and SECAM standards, converting composite or S-Video signals into digital ITU-R BT.656 formats. It also decodes component RGB/YPrPb signals for HDTV standards including 720p and 1080i. Graphics digitization supports resolutions up to 1024 × 768 at 70 Hz. Power supplies include AVDD (3.15 V to 3.45 V), DVDD (1.65 V to 2.0 V), and DVDDIO (3.0 V to 3.6 V). It operates within an industrial temperature range of −40°C to +85°C.

Feature Summary

• Integrates four 10-bit ADCs with internal antialias filters for high-quality signal conversion.
• Supports simultaneous processing of standard definition video and RGB graphics inputs.
• Includes adaptive digital line length tracking and proprietary locking architecture for unstable sources.
• Features certified Macrovision copy protection detection and vertical blanking interval data slicer.

Applications

• Automotive entertainment systems
• HDTVs and LCD/DLP projectors
• HDTV set-top boxes with PVR functionality
• DVD recorders with progressive scan input support

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and reel configuration. Ensure compatibility with required I2C addressing and power supply levels before integration. Confirm that the component meets the necessary automotive qualification standards if applicable to the target application environment.

Selection Notes

Select this component when both SDTV decoding and high-resolution RGB graphics digitization are required on a single chip. Consider the 64-lead LQFP package constraints and verify thermal performance under maximum load conditions. Evaluate power consumption across different input modes to ensure compliance with system energy requirements.

Part Context

This part belongs to the ADV7181C series of integrated video decoders. It serves as a bridge between analog video sources and digital processing units. The device replaces discrete decoder solutions by integrating multiple processing sections, including standard definition and component processors, into a compact form factor suitable for space-constrained designs.

Replacement Considerations

Check for direct pin-compatible alternatives within the same product family. Verify functional equivalence regarding supported video standards and output interfaces. Ensure substitute components meet the same thermal and electrical specifications for seamless integration.
