ADV7402AKSTZ-110

Overview

The ADV7402AKSTZ-110 is a single-chip multiformat video decoder and graphics digitizer featuring three 110 MHz noise-shaped 12-bit ADCs. It supports NTSC, PAL, and SECAM standards via composite or S-video inputs, converting them to digital ITU-R BT.656 format. The component processor handles YPrPb and RGB signals for HDTV formats including 525p, 625p, 720p, and 1080i. Graphics digitization supports RGB up to 1280 × 1024 @ 60 Hz. Power supplies are 1.8 V for the digital core and 3.3 V for analog/digital I/O.

Feature Summary

• Integrates three 110 MHz noise-shaped 12-bit ADCs with a 12-channel analog input multiplexer.
• Includes a standard definition processor with super adaptive 2D comb filters and automatic global standard detection.
• Features a component processor supporting any-to-any 3x3 color space conversion matrices.
• Provides a 24-bit digital input port compatible with DVI/HDMI receiver data streams.

Applications

• LCD/DLP rear projection HDTVs
• PDP HDTVs
• CRT HDTVs
• LCD/DLP front projectors
• Multiformat scan converters

Procurement Notes

Verify that the specific part number matches the required temperature range of -25°C to +70°C. Confirm the package type is the 100-lead LQFP (ST-100). Ensure compatibility with 1.8 V digital core and 3.3 V analog/digital I/O power supply requirements during system design validation.

Selection Notes

Select this component when a single chip solution is needed for both SDTV decoding and HDTV component processing. It is suitable for designs requiring RGB graphics digitization up to SXGA resolutions. The integrated color space converter and digital input port simplify interfaces with downstream encoders and HDMI transmitters.

Part Context

This device belongs to Analog Devices' high-quality video decoder family. It combines standard definition processing with high-definition component video handling in one package. The architecture utilizes noise-shaped oversampling to enhance signal-to-noise ratios while reducing external filter complexity.
