DS90UH940TNKDRQ1

Overview

The DS90UH940TNKDRQ1 is a dual-channel FPD-Link III deserializer manufactured by Texas Instruments, designed for automotive applications under AEC-Q100 qualification. It supports video resolutions up to 1080p at high frame rates and operates within an extended temperature range of -40°C to +105°C. The device features a WQFN-64 package suitable for surface mount installation. Key electrical parameters include a maximum data rate of 3.36 Gbps per lane, with support for multiple input lanes to aggregate camera data. Power supply requirements typically involve dual voltage rails, ensuring efficient operation in vehicle infotainment and driver assistance systems.

Feature Summary

• Dual-channel architecture enabling simultaneous processing of two independent video streams for multi-camera setups.
• FPD-Link III compatibility providing high-bandwidth, low-latency transmission over single-pair twisted shielded cable.
• Integrated CSI-2 to LVDS conversion facilitating direct interface with image sensors and downstream processors.

Applications

• Surround view monitoring systems requiring multiple camera inputs.
• Driver information clusters and digital instrument panels.
• Advanced driver assistance systems (ADAS) utilizing wide-angle or fisheye cameras.

Procurement Notes

Verify the specific suffix DR against the official datasheet to confirm packaging type and reel specifications. Ensure the component meets the required AEC-Q100 grade for automotive reliability standards. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm that the ordering quantity aligns with standard factory pack sizes if bulk procurement is intended.

Selection Notes

Select this model when dual-channel deserialization is required for 1080p video applications. Compare pinout and power requirements against alternative serializers like the DS90UH941 to ensure system compatibility. Consider the thermal performance of the WQFN-64 package in relation to the enclosure design. Validate that the cable length and signal integrity meet the FPD-Link III specifications for the chosen data rate.

Part Context

This component belongs to the DS90UH940 family of FPD-Link III deserializers from Texas Instruments. It is specifically engineered for automotive display interfaces, offering robust signal integrity and low power consumption. The device complements other members of the family, such as the DS90UB940, by providing dedicated dual-channel capabilities for complex visual processing tasks in modern vehicles.

Replacement Considerations

The DS90UH940TNKDTQ1 is a documented variant within the same functional family, differing primarily in packaging or tape-and-reel specifications. Verify pin-to-pin compatibility before substitution. Other family members like the DS90UB940 may offer similar functionality but require careful evaluation of channel count and interface types.
