X98021L128-3.3-Z

Overview

The X98021L128-3.3-Z is a triple-channel, 8-bit Analog Front End (AFE) designed for digitizing analog RGB or YUV graphics signals. It features a maximum conversion rate of 210MSPS and supports resolutions up to UXGA at 75Hz refresh rates. The device includes a digital PLL that generates pixel clocks from HSYNC or SOG signals, with output frequencies ranging from 10MHz to 210MHz. It operates on a single 3.3V supply and incorporates five embedded voltage regulators. Key specifications include programmable input bandwidth from 100MHz to 780MHz, 64 interpixel sampling positions, and automatic black level compensation.

Feature Summary

• Fully differential analog design providing high power supply rejection ratio and dynamic performance.
• Internal DC restore clamping with mid-scale capability for YUV signal processing.
• Automatic Black Level Compensation eliminates part-to-part offset variations.
• Digital PLL generates pixel clock from analog source sync signals.

Applications

• LCD Monitors
• Projectors
• Digital TVs
• Plasma Display Panels
• RGB Graphics Processing

Procurement Notes

Verify the component is the X98021L128-3.3-Z variant, which denotes the Pb-free plus anneal RoHS-compliant version in a 128-pin MQFP package. Confirm the operating temperature range matches commercial requirements of 0°C to +70°C. Ensure the datasheet revision aligns with FN8219 Rev 3.00 for accurate electrical specifications and pin descriptions.

Selection Notes

Select this component for applications requiring high-speed digitization of analog video signals up to 210MSPS. It is suitable for systems needing independent gain and offset control for each channel. Consider the 128-pin MQFP package constraints and the requirement for a single 3.3V supply with internal regulation when designing the power distribution network.

Part Context

Manufactured by Renesas Electronics Corporation (formerly Intersil), the X98021 is a specialized video digitizer. The 'Z' suffix indicates compliance with RoHS standards and Pb-free soldering operations. It is intended for use in display drivers and video processing units where precise analog-to-digital conversion is critical for image quality.

Replacement Considerations

The ISL98001-210 is documented as a 100% compatible improved alternative. Verify pinout compatibility and register mapping before substitution. No other direct substitutes are confirmed in the provided documentation.

FAQ

What is the function of the Automatic Black Level Compensation (ABLC)?

ABLC eliminates part-to-part offset variation, ensuring perfect black level performance across different applications and devices.

How does the Digital PLL handle sync signals?

The Digital PLL generates a pixel clock from the analog source's HSYNC or SOG (Sync-On-Green) signals, supporting frequencies from 10MHz to 210MHz.
