ADV7400KST-80

Overview

The ADV7400KST-80 is a multiformat video decoder integrating SDTV/HDTV decoding and RGB graphics digitization. It features true 10-bit data output accuracy via Noise Shaped Video ADCs, supporting conversion rates up to 110 MSPS for resolutions up to 1280x1024 @ 60 Hz. The device includes 12 analog input channels, supports NTSC, PAL, and SECAM standards, and handles HDTV inputs including 525p, 625p, 720p, and 1080i. It offers a configurable pixel output port with 8/10-bit 4:2:2 YCbCr or 16/20-bit 4:2:2 YCbCr options.

Feature Summary

• Integrates 12-channel analog input matrix with digital preprocessing and color space conversion
• Supports full component HDTV input and standard definition processing with adaptive comb filters
• Includes adaptive digital line length tracking for robust sync stability from nonstandard sources
• Features fully certified Macrovision detection and VBI data slicing for closed captioning

Applications

• Home theater projectors
• Direct view and rear projection HDTVs
• Consumer electronics designs requiring mixed-signal performance
• Systems replacing separate decoder and ADC chips

Procurement Notes

Verify the specific speed grade suffix (80) matches the required maximum conversion rate of 80 MHz for 1080i/720p applications. Confirm package type is LQFP-100 and check RoHS compliance status in current distributor listings. Ensure voltage supply requirements align with system design.

Selection Notes

Select this model over the ADV7402 if cost-sensitive applications require 10-bit accurate output rather than 12-bit precision. Choose the -80 speed grade when 1080i or 720p support is sufficient, avoiding higher-speed variants like -110 or -140 unless SXGA resolution at higher refresh rates is needed.

Part Context

Part of the ADV7402/ADV7400 family designed to simplify front-end digitizer architectures by reducing board space and power consumption. It consolidates functions previously handled by separate decoders and ADCs, enabling direct interfacing to scalers, MPEG codecs, and graphics processors.

Replacement Considerations

The ADV7402KST-80 serves as a higher-performance alternative with 12-bit ADCs. For lower speed requirements, the ADV7400KST-110 or ADV7400KST-140 offer higher resolution support.
