AD9887AKS-100

Specialized Overview

The AD9887AKS-100 is a display interface integrated circuit designed for flat panel displays, featuring dual 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 100 MSPS, a 330 MHz analog bandwidth, and an internal PLL generating pixel clocks from 12 MHz to 100 MHz. The digital interface is DVI 1.0 compatible, supporting operation up to 112 MHz in 1-pixel-per-clock mode. The device operates on a 3.3 V power supply, accepts analog inputs between 0.5 V and 1.0 V, and is housed in a 160-lead MQFP package.

Specialized Feature Summary

• Dual interface architecture allowing selection between analog RGB input and digital DVI input
• Integrated analog front-end with programmable gain, offset, and clamp control
• On-chip PLL generates pixel clock from HSYNC or accepts external clock input
• DVI 1.0 compatible receiver with high skew tolerance for digital video signals

Specialized Applications

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

Specialized Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific suffix matches the required performance grade. Check for obsolete status implications regarding long-term availability and support. Ensure ESD precautions are observed during handling due to sensitivity. Validate packaging integrity against moisture sensitivity levels before assembly.

Specialized Selection Notes

Select this model when SXGA resolution support at 75 Hz is required. Choose the analog interface path for standard VGA/SXGA RGB sources. Opt for the digital interface path for DVI-compliant sources. Ensure the system design accommodates the 160-lead MQFP package constraints. Verify power supply requirements align with the specified 3.3 V operating voltage.
