AD9887AKS-170

Specialized Overview

The AD9887AKS-170 is a display interface integrated circuit designed for flat panel displays, featuring both analog and digital interfaces on a single chip. It supports resolutions up to SXGA (1280 × 1024 at 75 Hz). The analog interface includes a triple ADC with a maximum conversion rate of 140 MSPS, a 330 MHz analog bandwidth, and an internal 1.25 V reference. The digital interface is DVI 1.0 compatible, supporting operation up to 112 MHz in 1 or 2 pixel/clock modes. The device operates on a 3.3 V power supply, draws 258 mA typical current, and is housed in a 160-lead MQFP package.

• LCD monitors and projectors
• Plasma display panels
• Scan converters
• Digital TVs

Specialized Procurement Notes

Verify the exact ordering suffix against the manufacturer's official documentation, as variations such as -100 or -140 indicate different performance specifications. Confirm that the component is sourced from authorized distributors to ensure authenticity, particularly given its obsolete status. Check for RoHS compliance details and moisture sensitivity levels prior to procurement.

Specialized Selection Notes

Select this component when a dual-mode interface solution is required for flat panel displays. Ensure the design accommodates the 160-lead MQFP package constraints. Verify that the system timing requirements align with the 140 MSPS analog and 112 MHz digital limits. Consider the 3.3 V power supply requirement and thermal characteristics during board layout.

Specialized Part Context

The AD9887 series provides a flexible interface solution for FPDs, allowing designers to choose between analog or digital inputs. It integrates full sync processing and midscale clamp functions. The device is fabricated in an advanced CMOS process and is specified over the 0°C to 70°C temperature range, targeting consumer and professional display applications.
