AD9984AKSTZ-170

Overview

The AD9984AKSTZ-170 is a high-performance display interface integrated circuit manufactured by Analog Devices. It features three monolithic 10-bit analog-to-digital converters (ADCs) with a maximum conversion rate of 170 MSPS and a full power analog bandwidth of 300 MHz. The device supports HDTV modes up to 1080p and graphics resolutions up to UXGA (1600 × 1200 at 60 Hz). It operates within an ambient temperature range of 0°C to +70°C and utilizes an 80-lead low-profile quad flat package (LQFP).

Feature Summary

• Integrates triple 10-bit ADCs with internal reference, programmable gain, offset, and clamp control.
• Includes an on-chip PLL for sample clock generation from tri-level or horizontal sync signals.
• Provides automatic gain matching and automated offset adjustment across channels.
• Supports variable output drive strength and multiple output format modes including 4:4:4, 4:2:2, and DDR.

Applications

• Advanced TVs
• Plasma display panels
• LCD monitors and projectors

Procurement Notes

Verify the specific suffix '170' against official documentation to confirm the 170 MSPS maximum conversion rate specification. Ensure the LQFP-80 package type matches the design requirements. Confirm RoHS compliance status through the manufacturer's current datasheet revision. Validate that the operating temperature range aligns with system environmental constraints.

Selection Notes

Select this component when capturing YPbPr video or RGB graphics signals requiring high-speed digitization. The device is suitable for systems needing integrated sync processing and clock generation without external components. Consider the 300 MHz analog bandwidth for signal integrity in high-resolution applications. Evaluate the serial register configuration capabilities for flexible system integration.

Part Context

The AD9984A series serves as a complete analog interface solution for digital displays. It consolidates input buffering, DC restoration, and data formatting into a single CMOS chip. This integration simplifies PCB layout and reduces sensitivity to electrical noise compared to discrete solutions.
