ADV7311KST

Overview

The ADV7311KST is a multiformat video encoder featuring six NSV 12-bit digital-to-analog converters. It supports simultaneous standard definition and high definition inputs, including 8-, 10-, 16-, and 20-bit parallel YCrCb data. The device operates with dual I/O supplies of 2.5 V/3.3 V and an analog supply of 2.5 V. It utilizes a 2-wire serial I²C interface for configuration and includes an on-board PLL. The component is housed in a 64-lead LQFP package.

Feature Summary

• Supports simultaneous SD and HD input/output formats
• Integrates six high-speed NSV video DACs
• Includes programmable filters and test pattern generators
• Features internal voltage reference and PLL

Applications

• High-end DVD players and recorders
• SD/HDTV set-top boxes
• Professional video systems
• SD/Progressive Scan/HDTV display devices

Procurement Notes

Verify the specific ordering suffix KST to confirm the 64-lead LQFP plastic quad flat package option. Ensure compatibility with lead-free soldering processes up to 255°C. Confirm that the ALSB pin configuration matches the required I²C address settings for the target system design.

Selection Notes

Select this model when both standard definition and high definition video encoding are required simultaneously. The ADV7311 differs from the ADV7310 by excluding Macrovision Rev 1.1 support for 525p/625p standards. Verify that the 12-bit resolution and 216 MHz oversampling capabilities meet the specific bandwidth requirements of the application.

Part Context

This component belongs to the ADV7310/ADV7311 family of multiformat video encoders manufactured by Analog Devices. These chips are designed to convert digital video data into analog signals for various display standards. The KST suffix specifically denotes the 64-lead LQFP package variant within this product line.

Replacement Considerations

The ADV7310KST is a direct functional substitute with identical packaging and specifications, except it lacks Macrovision Rev 1.1 support.
