AD9887AKS-140

Specialized Overview

The AD9887AKS-140 is a display interface integrated circuit manufactured by Analog Devices Inc. It provides dual analog and digital interfaces for flat panel displays, supporting resolutions up to SXGA (1280 × 1024 at 75 Hz). The device features a maximum conversion rate of 140 MSPS with a 330 MHz analog bandwidth. It operates on a 3.3 V power supply and includes an internal 1.25 V reference. The package is a 160-lead MQFP surface mount plastic variant. The operating temperature range is specified from 0°C to +70°C.

Specialized Feature Summary

• Dual interface architecture supporting both analog RGB inputs and DVI 1.0 compatible digital video reception on a single chip.
• Integrated analog front-end with triple ADCs, programmable gain, offset control, and midscale clamp capabilities.
• On-chip PLL generates pixel clocks from HSYNC signals, supporting frequencies from 12 MHz to 140 MHz.
• DVI receiver supports true color panels in 1 or 2 pixel/clock modes with high skew tolerance.

Specialized Applications

• RGB graphics processing systems
• LCD monitors and projectors
• Plasma display panels
• Scan converters
• Digital TV receivers

Specialized Procurement Notes

Verify component authenticity through authorized channels as the datasheet marks this model as obsolete. Confirm that the ordering suffix corresponds to the specific speed grade and package option required for the design. Ensure compliance with RoHS directives and check for moisture sensitivity handling requirements during storage and assembly.

Specialized Selection Notes

Select this component when a unified solution for both analog and digital flat panel inputs is required. The 140 MSPS speed grade suits applications needing support for SXGA resolutions. Consider the 160-lead MQFP package constraints for PCB layout. Verify that the 3.3 V supply voltage aligns with the system power architecture.

Specialized Part Context

This part belongs to the AD9887 family of display interface ICs designed for flat panel displays. It shares functional similarities with other variants like the AD9887KS-100 but differs in maximum conversion speed. The series is characterized by its ability to handle high-resolution video signals with integrated sync processing and clock generation capabilities.
