AD9985ABSTZ-110

Specialized Overview

The AD9985ABSTZ-110 is an 8-bit, 140 MSPS analog interface IC designed for flat panel displays. It features a 300 MHz analog bandwidth and accepts RGB inputs within a 0.5 V to 1.0 V range. The device includes an internal PLL generating pixel clocks from 12 MHz to 110 MHz with typical jitter of 500 ps p-p at 110 MSPS. Powered by a single 3.3 V supply, it dissipates approximately 500 mW. Outputs are three-state CMOS compatible with 2.5 V to 3.3 V logic levels. It operates over a temperature range of -40°C to +85°C in an 80-lead LQFP package.

Specialized Feature Summary

• Integrated triple ADC with programmable gain, offset, and clamp control for accurate signal digitization.
• On-chip PLL generates pixel clock from Hsync input, maintaining phase alignment during coast mode.
• Full sync processing capabilities including composite sync and sync-on-green support.
• Fully programmable via a 2-wire serial interface for system configuration.

Specialized Applications

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

Specialized Procurement Notes

Verify the specific suffix ABSTZ-110 against the manufacturer's current ordering guide to confirm availability and exact electrical grade. Check for End-of-Life status or Product Change Notifications as older revisions may be discontinued. Ensure the source document matches the requested part number exactly before procurement.

Specialized Selection Notes

Select this component when capturing RGB signals up to SXGA resolution (1280x1024 at 75 Hz) is required. The 140 MSPS rate supports high-resolution flat panel interfaces. Ensure the design accommodates the 3.3 V power supply requirement and utilizes the serial port for necessary gain and clamp adjustments.

Specialized Part Context

This device belongs to the AD9985 family of analog interface ICs. It is functionally similar to the AD9985AKSTZ-110 but may differ in thermal or electrical specifications based on the 'B' grade designation. Both share the same LQFP-80 package and core functionality for flat panel display applications.

Specialized Replacement Considerations

The AD9985AKSTZ-110 is a related variant within the same product family. Verify if the 'K' grade meets the specific performance requirements of the application before substituting. Pinout compatibility should be confirmed via datasheets.
