ADV7181CBSTZ

Overview

The ADV7181CBSTZ 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. Power requirements include AVDD of 3.15 V to 3.45 V, DVDD of 1.65 V to 2.0 V, and DVDDIO of 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 a 3x3 color space conversion matrix for YCrCb and RGB format translation.
• Features certified Macrovision copy protection detection and vertical blanking interval data slicing.

Applications

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

Procurement Notes

Verify the specific suffix 'BSTZ' against official documentation to confirm package type and lead-free status. Ensure supply chain sources provide valid RoHS compliance certificates. Confirm that the ordering information matches the exact Rev. E datasheet specifications for voltage ranges and pin configurations before finalizing procurement orders.

Selection Notes

Select this component when a single-chip solution is required for both SDTV decoding and HDTV component processing. It is suitable for designs needing RGB graphics digitization up to XGA resolutions alongside standard video inputs. Consider the 64-lead LQFP package constraints and verify power supply compatibility with the specified 1.8 V and 3.3 V rails during system architecture planning.

Part Context

This part belongs to the ADV7181C series of integrated video decoders. It serves as a comprehensive frontend processor for consumer electronics requiring multi-format video input handling. The device consolidates functions typically spread across multiple chips, including ADCs, comb filters, and timing recovery circuits, into a single CMOS architecture.

Replacement Considerations

Check for updated revisions within the ADV7181C family. Verify pinout compatibility if substituting with other Analog Devices video decoders. Ensure functional equivalence regarding supported video standards and output interfaces before replacing the component in existing designs.
