ADV7181CWBSTZ-REEL

Overview

The ADV7181CWBSTZ-REEL is a single-chip multiformat video decoder and 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 converts PAL, NTSC, and SECAM composite or S-Video signals into digital ITU-R BT.656 formats. It supports component video standards including 525i, 625i, 525p, 625p, 720p, and 1080i. Graphics digitization handles RGB inputs 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 in an industrial temperature range of −40°C to +85°C and is housed in a 64-lead LQFP package.

Feature Summary

• Supports automatic detection and decoding of NTSC, PAL, and SECAM standards from composite or S-Video inputs.
• Processes component YPrPb and RGB video signals for HDTV standards such as 720p and 1080i.
• Digitizes RGB graphics signals up to XGA resolution with color space conversion capabilities.
• Includes integrated VBI data slicer for teletext and closed captioning extraction.

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 ordering suffix REEL indicates tape and reel packaging configuration. Confirm the C suffix denotes the industrial temperature grade variant (-40°C to +85°C) compared to commercial options. Ensure compatibility with the required 28.63636 MHz crystal oscillator or external clock source for proper system timing operation.

Selection Notes

Select this component when simultaneous processing of standard definition composite video and high definition component signals is required. The device is suitable for designs needing SCART fast blank overlay functionality. Consider the 64-lead LQFP package constraints and thermal dissipation requirements for the specific PCB layout.

Part Context

This part belongs to the ADV7181 series of multiformat video decoders. It serves as a bridge between analog video sources and digital display processors. The WBSTZ suffix identifies the specific lead-free LQFP-64 package variant within the product line.

Replacement Considerations

ADV7181D is a pin-compatible alternative within the same family offering similar decoding capabilities.
