ADV7401BSTZ-80

Overview

The ADV7401BSTZ-80 is a single-chip multiformat video decoder and graphics digitizer featuring four 10-bit ADCs sampling up to 80 MHz. It supports NTSC, PAL, SECAM, and HDTV component standards with a 12-channel analog input mux. The device includes a standard definition processor for composite/S-video and a component processor for YPrPb/RGB signals. It digitizes RGB graphics up to SXGA resolution and provides a 24-bit digital input port for DVI/HDMI sources. Power supplies include DVDD (1.65 V to 2.0 V), AVDD (3.15 V to 3.45 V), and DVDDIO (3.0 V to 3.6 V).

Feature Summary

• Supports simultaneous processing of CVBS and SD RGB signals via SCART fast blank functionality.
• Includes internal antialias filters and superadaptive 2D comb filters for superior signal separation.
• Features a programmable 3x3 color-space conversion matrix for any-to-any format translation.
• Integrates a VBI data slicer supporting Teletext, VPS, VITC, and closed captioning extraction.

Applications

• LCD/DLP rear projection HDTVs
• HDTV set-top boxes with PVR capabilities
• Multiformat scan converters
• DVD recorders with progressive scan input support

Procurement Notes

Verify the specific speed grade suffix '80' corresponds to the 80 MHz maximum LLC1 frequency requirement. Confirm that the industrial temperature range (-40°C to +85°C) matches the application environment. Ensure the LQFP-100 package thermal resistance specifications are adequate for the target power dissipation levels under continuous operation.

Selection Notes

Select this variant when the design requires an 80 MHz pixel clock limit rather than higher speed grades. It is suitable for applications needing integrated graphics digitization alongside standard definition decoding. Verify compatibility with downstream interfaces requiring DDR or SDR pixel output formats supported by the component processor.

Part Context

This component belongs to the ADV7401 family of high-quality video decoders. It integrates both standard definition and component processing sections on a single chip. The device replaces discrete decoder and digitizer solutions by combining analog front-end multiplexing with digital post-processing capabilities in one package.
