ADV7181CWBSTZ

Overview

The ADV7181CWBSTZ is a multiformat SDTV/HDTV 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 for composite and S-Video inputs, as well as component formats including 525p, 625p, 720p, and 1080i. It digitizes RGB graphics 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), PVDD (1.71 V to 1.89 V), and DVDDIO (3.0 V to 3.6 V). It operates in an industrial temperature range of −40°C to +85°C and is housed in a 64-lead LQFP package.

Feature Summary

• Supports simultaneous processing of standard definition composite/S-video signals and high definition component/RGB graphics signals.
• Includes integrated SCART fast blank support for overlay functionality and internal antialias filters.
• Features a 3x3 color space conversion matrix and VBI data slicer for teletext and closed captioning extraction.

Applications

• Automotive entertainment systems
• HDTVs and LCD/DLP projectors
• HDTV set-top boxes with PVR capabilities

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet revision to confirm package type and automotive qualification status. Ensure that the supply voltage requirements match the system design constraints before finalizing procurement orders.

Selection Notes

Select this component when a single-chip solution is required for both SDTV decoding and HDTV/component signal processing. Consider the 64-lead LQFP package dimensions and the need for a 28.63636 MHz crystal oscillator during the hardware design phase.

Part Context

This part belongs to the ADV7181 series of video decoders from Analog Devices. It serves as a comprehensive frontend for video systems requiring conversion of various analog video standards into digital pixel streams for downstream processing or display.

Replacement Considerations

Consult the official Analog Devices ordering guide for confirmed substitute part numbers within the same family. Verify pin compatibility and electrical specifications before implementing any alternative components.
