Procurement Notes

Verify the complete part number including suffixes to ensure correct packaging and temperature grade. Confirm AEC-Q100 certification status for automotive compliance. Check moisture sensitivity level handling requirements during assembly. Validate pinout compatibility with existing PCB layouts. Ensure power supply voltages match specified ranges for stable operation.

Selection Notes

Select this component when dual FPD-Link III inputs are required for high-definition video processing. Consider the ten LVDS output count for driving multiple display panels or sensor interfaces. Evaluate the 64-WQFN package size against available board space constraints. Verify thermal performance within the -40°C to +105°C operating range for automotive environments.

Part Context

This device belongs to the DS90UH948-Q1 family of FPD-Link III deserializers from Texas Instruments. It serves as a key interface component bridging high-speed serial video links to parallel LVDS displays or processors. The TNKD suffix indicates specific packaging and testing configurations for automotive-grade reliability.

Replacement Considerations

Direct substitutes within the same family include other DS90UH948 variants with different suffixes for packaging or temperature grades. Cross-family replacements may require significant redesign due to pinout and feature differences.
