AD9984KSTZ-110

Overview

The AD9984KSTZ-110 is a high-performance 10-bit display interface integrated circuit manufactured by Analog Devices Inc. It features three analog-to-digital converters with a maximum conversion rate of 110 MSPS and an internal phase-locked loop (PLL). The device supports full-power analog bandwidth of 300 MHz, accommodating video modes up to 1080p and graphics resolutions up to UXGA. It operates on a +1.8V power supply for the core and accepts digital I/O voltages from 1.8V to 3.3V. The component is housed in an 80-pin lead-free LQFP surface-mount package.

Feature Summary

• Integrates triple 10-bit ADCs with automatic gain matching and offset adjustment capabilities.
• Includes an internal PLL for pixel clock generation derived from sync signals or external sources.
• Provides programmable output data formatting supporting 4:4:4, 4:2:2, and DDR modes.
• Features comprehensive sync processing for composite, separated, and sync-on-green inputs.

Applications

• Advanced televisions
• Plasma display panels
• LCD monitors and projectors
• HDTV input interfaces

Procurement Notes

Verify the specific suffix KSTZ-110 against the manufacturer's current ordering guide to confirm the 110 MHz maximum conversion rate specification. Ensure compatibility with the required 80-pin LQFP footprint during procurement planning. Confirm RoHS compliance status as indicated in the latest datasheet revision prior to finalizing orders.

Selection Notes

Select this component when capturing YPbPr or RGB graphics signals requiring digitization at rates up to 110 MSPS. It is suitable for designs needing integrated signal conditioning, including clamping and gain control, without external discrete components. Consider the 80-pin package size and thermal characteristics relative to the available board space and cooling requirements.

Part Context

This part belongs to the AD9984 family of display interface ICs designed for analog video capture. It serves as a bridge between analog video sources and digital processing units like FPGAs or ASICs. The device simplifies system design by consolidating ADCs, clock generation, and sync processing into a single monolithic solution optimized for flat-panel displays.

Replacement Considerations

Consult the official Analog Devices replacement matrix for verified substitute part numbers. Cross-reference pinouts and electrical specifications to ensure functional equivalence before implementation.
