AD9888KS-100

Specialized Overview

The AD9888KS-100 is a monolithic analog interface optimized for capturing RGB graphics signals from personal computers and workstations. It features an 8-bit, 170 MSPS triple ADC with a full-power analog bandwidth of 500 MHz, supporting resolutions up to 1600 × 1200 (UXGA) at 75 Hz. The device includes an internal 1.25 V reference phase-locked loop (PLL) to generate a pixel clock from HSYNC and COAST inputs, providing midscale clamping and programmable gain, offset, and clamp controls. It operates on a single 3.3 V power supply and utilizes a 128-lead MQFP surface-mount package.

Specialized Feature Summary

• Integrates a 170 MHz triple ADC with an internal PLL for pixel clock generation from HSYNC and COAST signals.
• Provides full sync processing capabilities including hot plug detect and composite sync handling.
• Features programmable gain, offset, and clamp controls alongside a 2:1 analog input multiplexer.
• Supports 4:2:2 output format mode and maintains data timing alignment through phase-adjusted outputs.

Specialized Applications

• RGB graphics processing
• LCD monitors and projectors
• Plasma display panels

Specialized Procurement Notes

Verify the specific ordering suffix against official documentation to confirm performance grade and temperature range. Ensure the component matches the exact part number required for the design specifications. Confirm compliance with relevant environmental standards before integration into the final product assembly.

Specialized Selection Notes

Select this model when a 100 MHz or 140 MHz maximum conversion rate is sufficient for the target resolution. Verify that the 500 MHz analog bandwidth meets the signal integrity requirements. Ensure the system design accommodates the 128-lead MQFP package dimensions and thermal characteristics specified in the datasheet.

Specialized Part Context

The AD9888 series serves as a complete analog front-end solution for flat panel displays. This specific variant belongs to the family of high-speed analog interfaces designed to simplify the capture of RGB graphics signals. It replaces discrete components by integrating ADCs, sync processing, and clock generation into a single monolithic CMOS chip.

Specialized Replacement Considerations

The AD9888KSZ-140 offers identical functionality with a tested maximum conversion rate of 140 MHz. Both models share the same pinout and feature set, differing primarily in their specified operating frequency limits within the 100/140 MSPS category.
