AD9883AKST-110

Specialized Overview

The AD9883AKST-110 is an 8-bit, 140 MSPS analog interface IC optimized for capturing RGB graphics signals. It features a 300 MHz analog bandwidth and accepts input voltages from 0.5 V to 1.0 V p-p. The device includes a PLL generating pixel clocks between 12 MHz and 110 MHz with typical jitter of 500 ps p-p at 110 MSPS. It operates on a single 3.3 V supply with typical power dissipation of 500 mW. The component is housed in an 80-lead LQFP package and supports industrial temperature ranges.

Specialized Feature Summary

• Integrates triple 8-bit ADCs with internal reference and programmable gain/offset controls
• Includes full sync processing capabilities for composite and sync-on-green signals
• Features on-chip PLL for pixel clock generation with coast mode support
• Supports hot plugging detection via dedicated sync detect functionality

Specialized Applications

• RGB Graphics Processing
• LCD Monitors and Projectors
• Plasma Display Panels
• Scan Converters
• Digital TV Systems

Specialized Procurement Notes

Verify the specific suffix '110' indicates the 110 MHz maximum conversion rate variant rather than the 140 MHz version. Confirm the package type matches the required 80-lead LQFP form factor. Ensure the operating temperature range aligns with system requirements, as this model specifies commercial or industrial limits depending on the exact sub-part designation.

Specialized Selection Notes

Select this model when the application requires a maximum pixel clock frequency of 110 MHz. Verify that the 0.5 V to 1.0 V input voltage range matches the source signal levels. Consider the 300 MHz bandwidth for high-frequency signal integrity. Ensure the design accommodates the 80-lead LQFP footprint and 3.3 V logic levels for serial control and data outputs.

Specialized Part Context

This component belongs to the AD9883A family of analog flat panel display interfaces. It serves as a bridge between analog RGB sources and digital display systems. The 'KST' suffix denotes the surface-mount LQFP package option. The '110' identifier distinguishes it from higher-speed variants within the same functional family.

Specialized Replacement Considerations

AD9883ABST-110Z offers extended temperature range compatibility. AD9883AKST-140 provides increased maximum conversion speed up to 140 MSPS. Verify pinout and register compatibility before substituting these variants.
