ADV7301AKST

Overview

The ADV7301AKST is a multiformat SD, progressive scan, and HDTV video encoder manufactured by Analog Devices Inc. It integrates six NSV™ 12-bit DACs for high-speed digital-to-analog conversion. The device supports simultaneous standard definition and high definition inputs and outputs with oversampling capabilities at 108 MHz or 148.5 MHz. It operates on dual I/O supplies of 2.5 V and 3.3 V, utilizing a 64-pin LQFP package. Static performance specifications include a resolution of 12 bits, integral nonlinearity of ±2.0 LSB, and differential nonlinearity ranging from -2.0 to +0.25 LSB under typical conditions.

Feature Summary

• Supports simultaneous standard definition and high definition input/output formats
• Integrates six Noise Shaped Video (NSV) precision 12-bit digital-to-analog converters
• Features an internal phase-locked loop and programmable oversampling filters
• Includes fully programmable YCrCb to RGB matrix and gamma correction

Applications

• High-end DVD players
• SD/Program Scan/HDTV display devices
• SD/Program Scan/HDTV set-top boxes
• SD/HDTV studio equipment

Procurement Notes

Verify the specific ordering suffix AKST against the manufacturer's current documentation to confirm the plastic quad flatpack package option and lead-free status. Ensure compatibility with the required 2-wire serial MPU interface voltage levels before integration into the design.

Selection Notes

Select this component when multiformat video encoding with simultaneous SD and HD processing is required. The device is suitable for designs needing integrated oversampling and precise color space conversion without external DACs. Verify that the 64-LQFP package dimensions fit the target PCB layout constraints.

Part Context

This part belongs to the ADV7300A/ADV7301A family of video encoders. The ADV7301AKST variant specifically excludes Macrovision Rev 1.0 support found in the ADV7300A model. Both share identical core functionality regarding video input handling, DAC architecture, and control interfaces.
