ADV7400AKSTZ-80

Overview

The ADV7400AKSTZ-80 is a 10-bit integrated multiformat SDTV/HDTV video decoder and RGB graphics digitizer. It features three analog-to-digital converters (ADCs) for simultaneous processing of luminance, chrominance, and color difference signals. The device supports standard definition television formats including NTSC, PAL, SECAM, and HDTV resolutions up to 1080i/576p. Operating at a maximum LLC1 frequency of 80 MHz, it provides DDR timing compliant with Philips standards. The component is housed in a 100-pin LQFP package and includes an embedded PLL for clock generation.

Feature Summary

• Integrates three ADCs for simultaneous Y/Cb/Cr signal conversion
• Supports multiformat decoding for SDTV and HDTV inputs
• Includes embedded phase-locked loop for clock recovery
• Provides RGB graphics digitization capabilities

Applications

• Advanced television systems
• Set-top boxes
• Video capture cards
• Digital signage displays

Procurement Notes

Verify the suffix -80 indicates the 80 MHz speed grade variant. Confirm the 100-LQFP package dimensions match the design footprint. Check RoHS compliance status on the official datasheet. Ensure supply chain sources provide original manufacturer documentation. Validate pinout compatibility with existing circuit schematics before integration.

Selection Notes

Select this component when multiformat SDTV and HDTV decoding is required in a single IC. Consider the 10-bit resolution for high-fidelity video processing needs. Evaluate the 80 MHz operating limit against system clock requirements. Compare power consumption specifications with alternative decoders. Assess the need for embedded PLL functionality versus external clock sources.

Part Context

This part belongs to the ADV7400 series of multiformat video decoders from Analog Devices. It serves as a lower-cost alternative to higher-end models like the ADV7402 while maintaining robust decoding capabilities. The series is designed for applications requiring versatile video input handling and digital conversion in compact form factors.

Replacement Considerations

The ADV7402 is a documented higher-performance alternative within the same family. Verify functional compatibility if substituting with other ADV74xx series variants. Check pinout alignment to ensure board layout adjustments are unnecessary. Review updated datasheets for any changes in electrical characteristics or supported formats.
