ADV7802BSTZ-80

Overview

The ADV7802BSTZ-80 is a high-quality, single-chip multiformat video decoder and graphics digitizer manufactured by Analog Devices. It integrates four noise-shaped video (NSV) 12-bit analog-to-digital converters (ADCs), a standard definition processor (SDP), and a component processor (CP). The device supports NTSC, PAL, and SECAM standards via composite or S-video inputs, converting them to digital ITU-R BT.656 format. It also decodes YPrPb and RGB component signals into digital pixel streams. Key specifications include a 36-bit digital output, 12-bit deep color processing, and support for interlaced-to-progressive conversion. The part operates with a digital core supply of 1.75 V to 1.85 V and an analog supply of 3.15 V to 3.45 V.

Feature Summary

• Integrates four 12-bit NSV ADCs with a 12-channel analog input multiplexer for direct connection of multiple video sources without external switching components.
• Features a standard definition processor with adaptive 3D comb filtering and 3D digital noise reduction for superior chrominance and luminance separation.
• Includes a component processor capable of handling YPrPb and RGB graphics signals, supporting formats from VGA to SXGA rates.
• Provides flexible output formatting with simultaneous interlaced and progressive parallel outputs and advanced time-base correction.

Applications

• AV receivers
• LCD HDTVs
• Projectors

Procurement Notes

Verify the specific suffix '80' against official documentation to confirm performance characteristics, as ordering suffixes may indicate variations in speed grade or testing parameters. Ensure compatibility with required power supply voltages and interface protocols before integration. Confirm package availability and lead times through authorized distributors.

Selection Notes

Select this component for designs requiring integrated decoding of SDTV and HDTV component signals alongside graphics digitization. The internal 12-channel mux simplifies board layout by eliminating external multiplexers. Consider the power consumption profiles across different sampling modes when designing thermal management solutions for the LQFP-176 package.

Part Context
