AD9984AKCPZ-170

Overview

The AD9984AKCPZ-170 is a high-performance display interface IC featuring three 10-bit analog-to-digital converters with a maximum conversion rate of 170 MSPS. It supports full power analog bandwidth up to 300 MHz, enabling capture of HDTV modes up to 1080p and graphics resolutions up to UXGA (1600 × 1200 at 60 Hz). The device operates on a 1.8 V analog supply and 3.3 V digital I/O supply, consuming approximately 740 mW typical power dissipation. It includes an internal PLL for clock generation, auto-offset control, and auto gain matching.

Feature Summary

• Integrates triple 10-bit ADCs with automatic gain matching and offset adjustment capabilities
• Features an on-chip PLL that generates sample clocks from sync signals or external sources
• Provides programmable output data formatting supporting 4:4:4, 4:2:2, and DDR modes
• Includes comprehensive sync processing for composite sync and sync-on-green applications

Applications

• Advanced TVs and LCDTVs
• Plasma display panels and LCD monitors
• HDTV and RGB graphics processing systems
• Projectors and scan converters

Procurement Notes

Verify the specific suffix 'CPZ' corresponds to the 64-lead LFCSP package variant as documented in the ordering guide. Confirm the '-170' designation aligns with the 170 MSPS maximum conversion rate specifications. Ensure compatibility with the required 1.8 V and 3.3 V power supplies during integration planning.

Selection Notes

Select this component when system requirements demand digitization of YPbPr or RGB signals at resolutions up to 1080p or UXGA. The integrated PLL simplifies clocking architecture by eliminating external clock generators. Consider the 64-lead LFCSP package for space-constrained designs requiring surface-mount assembly.

Part Context

This part belongs to the AD9984A family of display interface ICs designed for capturing analog video signals. The AD9984A series provides complete signal conditioning including clamping, gain adjustment, and sync processing. It serves as a bridge between analog video sources and digital display processors or FPGAs.
