MAX9539EUI+

Video Processing Overview

The MAX9539EUI+ is a graphics video sync adder from the Analog Devices / Maxim Integrated MAX9539/MAX9540 chipset. It converts a 5-wire RGBHV interface to a 3-wire RGB interface by mixing horizontal and vertical sync signals into the video channels. The device features a DC restore function, an 180MHz large-signal bandwidth, and operates over an extended temperature range of -40°C to +85°C in a 28-pin TSSOP package.

Video Processing Feature Summary

• Converts 5-wire RGBHV input to a 3-wire RGB output by adding H and V sync signals
• Includes DC restore function to eliminate black level changes
• Utilizes proprietary true sync addition/extraction scheme to minimize skew errors

Video Processing Applications

• Enterprise Class (Blade) Servers
• Laptop PCs
• Keyboard-Video-Mouse (KVM)

Video Processing Procurement Notes

Verify the component is the lead-free version indicated by the '+' suffix. Confirm the 28-pin TSSOP package matches the design requirements. Ensure the operating environment falls within the specified -40°C to +85°C range for reliable performance.

Video Processing Selection Notes

Select this part when reducing channel count from RGBHV to RGB is required without introducing timing skew. It pairs with the MAX9540 extractor to complete the signal conversion path. Verify that the 180MHz bandwidth meets the resolution needs of the target display system.

Video Processing Part Context

This component belongs to the MAX9539/MAX9540 chipset designed for graphics video applications. It serves as the sync adder counterpart to the MAX9540 sync extractor. Both devices are specified for VGA-to-UXGA resolutions up to 1600 x 1200 at 85Hz.

Video Processing Replacement Considerations

The MAX9539EUI is the non-leaded equivalent of the MAX9539EUI+. No other direct substitutes are documented in the provided datasheet.
