ADV7181DWBCPZ-RL

Overview

The ADV7181DWBCPZ-RL is a multiformat video decoder and RGB graphics digitizer manufactured by Analog Devices Inc. It features four 10-bit ADCs sampling up to 75 MHz and supports ten analog input channels for composite, S-video, component, and RGB signals. The device converts NTSC, PAL, and SECAM standards into digital ITU-R BT.656 formats and handles HDTV resolutions including 720p and 1080i. It digitizes RGB graphics up to XGA at 70 Hz. Power supplies include DVDD (1.65 V to 2.0 V), DVDDIO (3.0 V to 3.6 V), AVDD (3.15 V to 3.45 V), and PVDD (1.71 V to 1.89 V). Operating temperature ranges from −40°C to +85°C.

Feature Summary

• Integrates four 10-bit ADCs with a 10-channel multiplexer for multisource connectivity without external switching components.
• Supports simultaneous processing of standard definition composite/S-video and high-definition component/RGB graphics signals.
• Includes dedicated Standard Definition Processor and Component Processor sections for independent signal handling.
• Features integrated color space conversion matrix and vertical blanking interval data slicer for teletext and closed captioning.

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 WBCPZ-RL against the manufacturer's current datasheet revision C documentation. Confirm that the reel packaging designation matches the required manufacturing line specifications. Ensure the automotive qualification status aligns with the intended deployment environment requirements before finalizing procurement orders.

Selection Notes

Select this component when a single-chip solution is required for decoding multiple analog video standards alongside RGB graphics digitization. The internal 10-channel mux eliminates the need for external multiplexers. Verify that the system design accommodates the specified multi-voltage power supply rails and the 64-lead LFCSP package thermal constraints.

Part Context

This part belongs to the ADV7181 family of video decoders. The ADV7181D variant specifically adds RGB graphics digitization capabilities compared to earlier models like the ADV7181. The device serves as a bridge between legacy analog video sources and modern digital display processors or HDMI transmitters.

FAQ

What is the maximum resolution supported for RGB graphics digitization?

The ADV7181D supports RGB graphics inputs up to 1024 × 768 pixels at a refresh rate of 70 Hz (XGA).

How does the device handle synchronization for component video inputs?

It supports embedded synchronization or separate HS, VS, or CS signals. A synchronization source polarity detector determines the source and polarity of accompanying sync signals.

What output interface formats are available for pixel data?

The device provides 12-bit 4:4:4 DDR, as well as 8-, 10-, 16-, and 20-bit SDR pixel output interfaces compatible with various downstream processor requirements.
