ADV7181CBCPZ

Overview

The ADV7181CBCPZ is a single-chip multiformat SDTV video decoder and RGB graphics digitizer manufactured by Analog Devices. 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 into digital YCrCb or RGB pixel streams, supporting resolutions up to 1280 × 1024 at 60 Hz. Operating within an industrial temperature range of −40°C to +85°C, it utilizes a 64-lead LFCSP_VQ package.

Feature Summary

• Integrates four 10-bit ADCs with internal antialias filters for high-quality signal conversion.
• Supports simultaneous processing of CVBS and standard definition RGB signals for SCART compatibility.
• Includes a 3x3 color space conversion matrix for flexible YCrCb and RGB output formatting.
• Features Adaptive Digital Line Length Tracking (ADLLT) for stable decoding of weak or noisy sources.

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 suffix CBCPZ against the manufacturer's current ordering guide to confirm package type and lead-free status. Confirm that the required external components, such as the 28.63636 MHz crystal and loop filter capacitors, are included in the system design. Ensure power supply voltages match the specified ranges for AVDD, DVDD, and DVDDIO before integration.

Selection Notes

Select this component when a single chip must handle both standard definition TV decoding and high-resolution RGB graphics digitization. It is suitable for designs requiring SCART fast blank overlay functionality. Consider the 64-lead package size and thermal requirements if operating near the upper limits of the industrial temperature range.

Part Context

This part belongs to the ADV7181C family of video decoders. It serves as a bridge between analog video sources and digital display processors. The device replaces discrete decoder and scaler solutions, reducing board space and component count in multimedia applications.

Replacement Considerations

Check for updated revisions from Analog Devices. Verify pin compatibility if substituting with other ADV7181 variants.
