ADV7401BSTZ-110

Overview

The ADV7401BSTZ-110 is a single-chip multiformat video decoder and RGB graphics digitizer featuring four 10-bit ADCs sampling up to 110 MHz. It supports NTSC, PAL, and SECAM standards via composite or S-video inputs, and decodes component RGB/YPrPb signals including 525p/625p progressive scan and 720p/1080i HDTV formats. The device digitizes RGB graphics up to 1280 × 1024 @ 75 Hz (SXGA). It includes a 24-bit digital input port for DVI/HDMI Rx IC data, a 3 × 3 color-space conversion matrix, and outputs 12-bit 4:4:4 or 8-bit 4:2:2 DDR pixel data.

Feature Summary

• Supports simultaneous processing of standard definition composite/S-video and high definition component video with automatic format detection.
• Digitizes RGB graphics signals from VGA to SXGA resolutions using internal antialias filters and clamp control loops.
• Features a 24-bit digital input port capable of receiving data directly from DVI or HDMI receiver integrated circuits.
• Includes an integrated VBI data slicer for extracting teletext, closed captioning, and copy generation management system data.

Applications

• LCD/DLP rear projection HDTVs
• HDTV set-top boxes with personal video recorder functionality
• Multiformat scan converters
• Hard-disk-based video recorders

Procurement Notes

Verify the specific speed grade suffix '110' corresponds to the 110 MHz maximum LLC1 frequency requirement for your design. Confirm that the LQFP package thermal characteristics meet your system's junction temperature calculations under maximum operating conditions. Ensure external loop filter components match the datasheet recommendations for stable PLL operation.

Selection Notes

Select this part when a combined SDTV decoder and HD graphics digitizer is required in a single package. The 110 MHz speed grade is suitable for SXGA graphics and standard HDTV component inputs but does not support the full 140 MHz bandwidth available in higher speed grades. Verify compatibility with downstream interfaces requiring 12-bit 4:4:4 or 8-bit 4:2:2 DDR pixel output formats.

Part Context

This component belongs to the ADV7401 family of multiformat video decoders. The BSTZ-110 variant specifically denotes the industrial temperature range (-40°C to +85°C) and the 110 MHz maximum sampling speed grade. It shares functional architecture with the -80 and -140 speed variants, differing primarily in maximum clock frequency capabilities.
