AD9983AKSTZ-140

Specialized Overview

The AD9983AKSTZ-140 is an 8-bit display interface IC from Analog Devices, designed for capturing YPbPr video and RGB graphics signals. It features three 140 MSPS analog-to-digital converters with a full power analog bandwidth of 300 MHz, supporting HDTV modes up to 1080i and 720p, and graphics resolutions up to SXGA (1280 x 1024 at 75 Hz). The device includes an internal PLL generating sample clocks from 10 MHz to 140 MHz, auto-offset adjustment, and automatic gain matching. It operates on a single 1.8 V supply for analog/digital logic and accepts 1.8 V to 3.3 V for outputs. Packaged in an 80-lead LQFP, it functions within a 0°C to +70°C temperature range.

Specialized Feature Summary

• Integrates triple 8-bit ADCs with 140 MSPS conversion rate and 300 MHz analog bandwidth
• Includes on-chip PLL for pixel clock generation with 32-step phase adjustment
• Features automated offset calibration and channel-to-channel gain matching
• Supports variable output drive strength and multiple output data formats

Specialized Applications

• Advanced TVs and HDTV systems
• Plasma display panels and LCD monitors
• RGB graphics processing and scan converters

Specialized Procurement Notes

Verify component authenticity through authorized channels as the AD9983AKSTZ-140 has reached end-of-life status. Confirm package integrity and pin alignment against the 80-lead LQFP specification before integration. Ensure compliance with RoHS directives and check for any specific handling requirements related to moisture sensitivity levels during storage and assembly processes.

Specialized Selection Notes

Select this component when designing systems requiring high-speed digitization of analog video or graphics signals up to SXGA resolution. It is suitable for applications needing integrated sync processing and clock regeneration without external discrete components. Consider the 80-lead LQFP footprint and thermal characteristics during PCB layout planning to ensure adequate heat dissipation within the specified operating temperature range.
