DS90UH940NTNKDTQ1

Overview

The DS90UH940NTNKDTQ1 is a dual-channel FPD-Link III deserializer manufactured by Texas Instruments, designed for automotive applications under AEC-Q100 qualification. It accepts two differential LVDS or FPD-Link III inputs and converts them into four independent CSI-2 output lanes. The device supports data rates up to 3.36 Gbps per lane, enabling high-resolution video transmission. It operates within a supply voltage range of 1.71V to 1.89V for the core and 3V to 3.6V for I/O, with an operating temperature range of -40°C to 105°C. The component is housed in a 64-pin WQFN package measuring 9x9 mm.

Feature Summary

• Dual-channel architecture supporting simultaneous processing of two independent video streams
• Conversion from FPD-Link III/LVDS input interfaces to MIPI CSI-2 digital outputs
• Integrated diagnostic capabilities including CRC error checking and link integrity monitoring

Applications

• Automotive surround view camera systems
• Advanced driver assistance system (ADAS) imaging modules
• In-vehicle infotainment display interfaces

Procurement Notes

Verify the specific suffix 'TNKDTQ1' against the official Texas Instruments datasheet to confirm pinout and electrical characteristics match the design requirements. Ensure the component meets AEC-Q100 Grade 1 specifications for the intended automotive environment. Cross-reference the manufacturing date code and lot traceability with authorized distributors to maintain supply chain integrity and quality assurance standards.

Selection Notes

Select this component when a dual-input deserialization solution is required for FPD-Link III cameras. Confirm that the target application utilizes MIPI CSI-2 compatible image sensors. Evaluate power consumption constraints against the specified 1.2V, 1.8V, and 3.3V rail requirements. Ensure the PCB layout accommodates the 64-WQFN package dimensions and thermal dissipation needs for the -40°C to 105°C operating range.

Part Context

This part belongs to the DS90UB940/DS90UH940 family of FPD-Link III deserializers. It serves as the receiver end of the link, complementing serializers like the DS90UH941. The 'Q1' designation indicates automotive qualification. It is distinct from non-automotive variants and earlier generation FPD-Link devices, offering higher bandwidth and improved diagnostic features suitable for modern vehicle architectures.

Replacement Considerations

Direct substitutes include other DS90UB940 series variants with compatible pinouts and electrical specs. Verify if alternative packages or temperature grades are available from Texas Instruments. Ensure any replacement maintains AEC-Q100 certification and supports the same 3.36 Gbps data rate and CSI-2 output configuration.
