DS90UH948TNKDRQ1

Overview

The DS90UH948TNKDRQ1 is a dual-channel FPD-Link III deserializer designed for automotive applications, certified to AEC-Q100 standards. It accepts two serial inputs and provides eight LVDS outputs, supporting data rates up to 3.36 Gbps per lane. The device operates on supply voltages of 1.71V to 1.89V and 3V to 3.6V, with an operating temperature range of -40°C to 105°C. Packaged in a 64-WQFN (9x9 mm) with exposed pad, it facilitates high-bandwidth video transmission from cameras to displays in advanced driver-assistance systems.

Feature Summary

• Supports dual-channel FPD-Link III input for high-resolution video streams
• Converts serial data to eight parallel LVDS output channels
• Integrated I2C/SPI interface for system configuration and control
• Automotive-grade reliability with extended temperature operation

Applications

• Advanced Driver-Assistance Systems (ADAS) camera interfaces
• Surround view monitoring systems
• In-Vehicle Infotainment (IVI) display drivers
• Digital cockpit rear-view mirror replacements

Procurement Notes

Verify the complete part number including suffixes such as TNKDRQ1 to ensure correct package, tape-and-reel quantity, and automotive qualification level. Confirm RoHS compliance status and moisture sensitivity level requirements prior to ordering. Cross-reference manufacturer datasheets for specific packaging options like cut tape or reel quantities to match assembly line needs.

Selection Notes

Select this component when dual-camera inputs require conversion to multiple parallel LVDS outputs for display processing. Ensure the host processor supports the required LVDS signaling and that power supply rails match the specified 1.8V and 3.3V domains. Verify thermal management capabilities for the WQFN package within the intended operating temperature range.

Part Context

This device belongs to the DS90UB948/DS90UH948 family of FPD-Link III deserializers. It complements serializers like the DS90UB960 series to form complete video links. The Q1 suffix denotes automotive qualification, distinguishing it from commercial variants. It serves as a critical bridge between front-end sensors and backend image processors in modern vehicle architectures.

Replacement Considerations

Direct substitutes include other DS90UH948 variants with different suffixes indicating package or tape options. Check compatibility with existing serializer devices in the link. Ensure pinout and register configurations remain identical when swapping between family members.
