SN75DP122ARTQR

Specialized Overview

The SN75DP122ARTQR is a DisplayPort 1:2 switch manufactured by Texas Instruments, housed in a 56-pin QFN package. It integrates a TMDS translator to support DVI and HDMI source inputs alongside DisplayPort sources. The device operates within a temperature range of 0°C to 85°C. It features an I2C interface for configuration and control. The component supports high-speed data transmission required for DisplayPort and TMDS signals, enabling flexible display connectivity solutions.

Specialized Feature Summary

• Integrates a TMDS translator to convert DVI or HDMI source signals for DisplayPort downstream devices
• Functions as a 1:2 switch allowing selection between two DisplayPort sources or one DP source and one TMDS source
• Configurable via I2C interface for dynamic input switching and system control

Specialized Applications

• DisplayPort docking stations requiring multiple video input selection
• All-in-one PCs with mixed DisplayPort and legacy DVI/HDMI input capabilities
• Monitor designs supporting both native DisplayPort and translated TMDS sources

Specialized Procurement Notes

Verify the specific ARTQR suffix against the manufacturer's official datasheet to confirm the exact tape-and-reel packaging quantity and moisture sensitivity level. Ensure the ordering part number matches the required commercial temperature grade and pin configuration before finalizing procurement documentation.

Specialized Selection Notes

Select this component when a design requires switching between two DisplayPort sources or integrating a DVI/HDMI source into a DisplayPort sink architecture. Confirm that the system voltage levels and I2C addressing requirements align with the integrated translator specifications provided in the technical documentation.

Specialized Part Context

This part belongs to the SN75DP12x series of display interface ICs from Texas Instruments. It is designed specifically for applications needing signal path flexibility between modern DisplayPort standards and legacy TMDS-based interfaces like DVI and HDMI within a single compact package.

Specialized Replacement Considerations

The SN75DP122A is a variant within the same family. Verify if the 'A' suffix indicates any functional differences or updated manufacturing revisions compared to the standard SN75DP122ARTQR before substitution.
