AD9883AKSTZ-RL110

Specialized Overview

The AD9883AKSTZ-110 is an 8-bit, 140 MSPS analog interface IC designed for flat panel displays. It features a maximum conversion rate of 110 MSPS and a 300 MHz full-power analog bandwidth. The device accepts analog input voltages between 0.5 V and 1.0 V p-p. It operates on a single 3.3 V power supply with typical power dissipation of 500 mW. The unit includes an internal PLL generating pixel clocks from 12 MHz to 140 MHz, with typical jitter of 500 ps p-p at 110 MSPS. It utilizes an 80-lead LQFP package and supports the 4:2:2 output format.

Specialized Feature Summary

• Integrates triple 8-bit ADCs with programmable gain, offset, and clamp control for RGB signal digitization.
• Includes an on-chip PLL that generates pixel clocks from Hsync inputs and maintains frequency via COAST signals.
• Provides full sync processing capabilities including composite sync and sync-on-green handling.

Specialized Applications

• RGB Graphics Processing
• LCD Monitors and Projectors
• Plasma Display Panels

Specialized Procurement Notes

Verify the specific suffix Z indicates lead-free compliance and ST-80 denotes the 80-lead LQFP package. Confirm the -110 designation aligns with the 110 MSPS maximum conversion rate specification rather than the 140 MSPS variant. Ensure the industrial temperature range requirements match the component's rated operating conditions.

Specialized Selection Notes

Select this model when a 110 MSPS sampling rate is sufficient for the target resolution. Verify compatibility with 3.3 V logic levels for digital outputs. Consider the 80-lead LQFP footprint constraints during PCB layout. Evaluate if the integrated PLL and clamping functions meet system design requirements without external components.

Specialized Part Context

This component belongs to the AD9883A series of display interface ICs manufactured by Analog Devices. It serves as a monolithic solution for capturing analog RGB graphics signals from personal computers and workstations. The device integrates necessary buffering, DC restoration, and clock generation to simplify system design for flat panel display applications.

Specialized Replacement Considerations

The AD9883ABST-110 offers the same electrical specifications but supports an extended industrial temperature range of –40 °C to +85°C compared to the commercial range of the AKST variant.
