ADV7402KST-110

Overview

The ADV7402KST-110 is a multiformat video decoder and RGB graphics digitizer featuring three 110 MHz noise-shaped 12-bit ADCs. It supports NTSC, PAL, SECAM, and HDTV component standards (525i to 1080i). The device digitizes RGB graphics up to 1280 × 1024 @ 60 Hz and includes a 24-bit digital input port for DVI/HDMI Rx data. Power supplies are 1.8 V for the digital core and 3.3 V for analog/digital I/O. Operating temperature ranges from −25°C to +70°C.

Feature Summary

• Integrates three 110 MHz noise-shaped 12-bit ADCs with a 12-channel analog input multiplexer.
• Includes Standard Definition Processor (SDP) for composite/S-video decoding and Component Processor (CP) for YPrPb/RGB processing.
• Features any-to-any 3 × 3 color space conversion matrix and certified Macrovision detection.
• Supports digital video input ports for raw CVBS or 24-bit RGB data from DVI/HDMI receivers.

Applications

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

Procurement Notes

Verify that the specific order suffix KST-110 corresponds to the -25°C to +70°C industrial temperature range and ST-100 LQFP package as documented in the Analog Devices ordering guide. Confirm RoHS compliance and Pb-free lead finish specifications match project requirements before finalizing procurement.

Selection Notes

Select this component when a single-chip solution is required for both standard definition composite decoding and high-definition component video digitization. It is suitable for designs needing integrated RGB graphics capture up to SXGA resolution alongside dedicated digital inputs for HDMI/DVI receiver interfacing.

Part Context

The ADV7402KST-110 belongs to the ADV7402 family of multiformat video decoders. It combines SD video decoding capabilities with HD component video processing and RGB graphics digitization on a single die, utilizing a 100-pin LQFP package.

Replacement Considerations

Consult the manufacturer's official obsolescence notices and cross-reference lists for verified substitute part numbers. Do not assume functional equivalence with other models without verifying pinout and specification compatibility.
