DS90UH940NTNKDRQ1

Overview

The DS90UH940NTNKDRQ1 is a dual FPD-Link III to CSI-2 deserializer designed for automotive applications. It supports data rates up to 3.36 Gbps per lane, enabling high-resolution video transmission. The device features two FPD-Link III inputs and four MIPI CSI-2 outputs. It operates within a supply voltage range of 1.71V to 1.89V for the core and 3V to 3.6V for I/O. The component is qualified to AEC-Q100 standards and functions reliably across an ambient temperature range of -40°C to +105°C. It is housed in a 64-pin WQFN package.

Feature Summary

• Supports dual FPD-Link III input links for high-bandwidth video data reception
• Converts serialized video streams into parallel MIPI CSI-2 output signals
• Integrated clock recovery circuitry for robust signal integrity over long cable runs
• Automotive-grade qualification ensuring reliability in harsh environmental conditions

Applications

• Surround view camera systems in vehicles
• Digital rear-view mirror displays
• In-cabin monitoring cameras
• ADAS sensor fusion units

Procurement Notes

Verify the specific suffix 'TNKDRQ1' against the manufacturer's latest datasheet to confirm pinout compatibility and packaging type. Ensure that the ordering information matches the required tape-and-reel quantity specifications. Cross-reference the AEC-Q100 grade requirements with your system's reliability standards before finalizing procurement decisions.

Selection Notes

Select this component when dual FPD-Link III inputs are required to drive multiple MIPI CSI-2 lanes. Compare against the DS90UB940 series if single-link or different output configurations are needed. Verify that the 64-WQFN thermal performance meets your PCB design constraints. Confirm that the target application requires the specific data rate capabilities defined in the official specification sheet.

Part Context

This part belongs to the Texas Instruments DS90UH940-Q1 family of automotive serializers and deserializers. It is specifically engineered for FPD-Link III technology, which is widely used in automotive vision systems. The device complements other members of the family, such as the DS90UH947 serializer, to form complete video link solutions.

Replacement Considerations

Publicly confirmed substitutes include DS90UH940TNKDTQ1 and DS90UB940TNKDTQ1. Verify functional equivalence regarding input/output counts and electrical characteristics before substitution.
