AD9984KSTZ-140

Overview

The AD9984KSTZ-140 is a high-performance 10-bit display interface featuring three integrated analog-to-digital converters. It supports a maximum conversion rate of 140 MSPS and includes an internal phase-locked loop for clock generation. The device accepts YPbPr or RGB graphics signals with input voltage ranges from 0.5 V to 1.0 V peak-to-peak. It operates on a 1.8 V analog supply and a 1.8 V to 3.3 V digital output supply, housed in an 80-pin LQFP package.

Feature Summary

• Integrates triple 10-bit ADCs with automatic gain matching and offset adjustment capabilities
• Includes an internal PLL for pixel clock generation with programmable sampling phase adjustment
• Provides comprehensive sync processing for composite, separated, and sync-on-green signals
• Supports variable output drive strength and multiple output data format modes

Applications

• Advanced televisions and HDTV systems
• Plasma display panels (PDP)
• LCD monitors and projectors
• RGB graphics processing units
• Scan converters

Procurement Notes

Verify the specific suffix KSTZ-140 against the manufacturer's current ordering guide to confirm the 140 MHz speed grade. Ensure the procurement source provides valid RoHS compliance documentation and confirms the Pb-free package status as specified in the technical data sheet.

Selection Notes

Select this component when capturing YPbPr or RGB signals requiring digitization up to 140 MSPS. It is suitable for designs needing integrated sync processing and automatic signal calibration features without external discrete components for gain or offset control.

Part Context

This part belongs to the AD9984 family of display interfaces designed by Analog Devices. It is functionally similar to the AD9984AKCPZ-140 but utilizes an 80-pin LQFP package instead of an LFCSP-64 package. Both variants share identical electrical specifications regarding resolution and bandwidth.

Replacement Considerations

The AD9984AKCPZ-140 serves as a functional equivalent within the same product family, offering identical performance metrics but differing only in the surface mount package type.
