AD9887KS-100

Specialized Overview

The AD9887KS-100 is a display interface integrated circuit designed for flat panel displays, featuring both analog and digital interfaces on a single chip. It includes a triple analog-to-digital converter with an internal 1.25 V reference and a DVI 1.0 compatible receiver. The device supports resolutions up to SXGA (1280 × 1024 at 75 Hz). Key electrical parameters include a maximum conversion rate of 100 MSPS, an analog bandwidth of 330 MHz, and an input voltage range of 0.5 V to 1.0 V p-p. It operates on a 3.3 V power supply with a typical total supply current of 258 mA. The component is housed in a 160-lead MQFP plastic package and functions within a temperature range of 0°C to 70°C.

Specialized Feature Summary

• Integrates a fully analog interface with a triple ADC, PLL clock generation, and full sync processing capabilities.
• Includes a Digital Visual Interface (DVI 1.0) compatible receiver supporting true color panels in 1 or 2 pixel/clock modes.
• Features high skew tolerance of one full input clock cycle for the digital interface.
• Provides programmable gain, offset, and clamp control via a 2-wire serial interface.

Specialized Applications

• RGB graphics processing
• LCD monitors and projectors
• Plasma display panels
• Scan converters
• Micro displays

Specialized Procurement Notes

Verify the obsolete status of this component before procurement planning. Confirm availability through authorized distributors or secondary market suppliers. Ensure that the specific KS-100 suffix matches the required 100 MSPS performance level rather than the higher speed variant. Check for RoHS compliance documentation and moisture sensitivity handling requirements during storage and assembly.

Specialized Selection Notes

Select the AD9887KS-100 when a dual-mode interface solution is required for flat panel displays supporting up to SXGA resolution. This model is appropriate for designs needing a 100 MSPS maximum conversion rate. Consider the AD9887KS-140 if a higher 140 MSPS conversion rate is necessary for the application. Ensure the design accommodates the 160-lead MQFP package constraints and thermal characteristics.

Specialized Part Context

The AD9887 series serves as a comprehensive interface solution for connecting various video sources to flat panel displays. It consolidates analog signal conditioning and digital reception into one component, reducing board space and design complexity. The AD9887KS-100 specifically targets applications requiring a 100 MSPS sampling rate, distinguishing it from the faster KS-140 variant within the same product family.

Specialized Replacement Considerations

Public confirmed substitute part numbers are not available in the provided datasheet. Designers should evaluate the AD9887KS-140 for higher performance needs or consult Analog Devices for current portfolio alternatives due to the obsolete status of this component.
