DS90UH949TRGCRQ1

Overview

The DS90UH949TRGCRQ1 is an automotive-grade serializer from Texas Instruments, designed for FPD-Link III applications. It converts MIPI DSI video data into a high-speed serial link. The device supports up to 3.675 Gb/s data rates with eight LVCMOS inputs and four LVDS outputs. It operates within a supply voltage range of 1.045 V to 1.89 V and consumes approximately 300 mA. Certified under AEC-Q100, it functions between -40°C and +105°C in a 64-pin VQFN package.

Feature Summary

• Converts parallel MIPI DSI signals to serial FPD-Link III output
• Supports dual-lane or quad-lane MIPI DSI input configurations
• Integrated clock recovery and synchronization circuitry
• Automotive qualification compliant for harsh environment operation

Applications

• Automotive surround view camera systems
• Digital rear-view mirror displays
• In-cabin infotainment video interfaces
• ADAS sensor data transmission links

Procurement Notes

Verify the complete part number including the suffix TRGCRQ1 to ensure correct packaging and automotive grade status. Confirm RoHS compliance and moisture sensitivity level requirements before ordering. Check for specific revision levels if integrating with existing reference designs. Ensure ESD protection measures are adequate during handling due to the VQFN package type.

Selection Notes

Select this component when interfacing MIPI DSI sources with FPD-Link III deserializers in automotive environments. It is suitable for applications requiring high bandwidth video transmission over long cable runs. Consider pin compatibility with similar serializers like the DS90UH929 if lower resolution is sufficient. Verify power supply constraints match the 1.1V and 1.8V rails specified in the datasheet.

Part Context

This device belongs to the DS90UH949A family of bridge serializers. It complements deserializers such as the DS90UB949-Q1 in complete video link solutions. The series is optimized for automotive display and camera applications requiring reliable, high-speed data transfer. It serves as a key interface between image sensors and processing units in modern vehicle architectures.

Replacement Considerations

The DS90UH949ATRGCRQ1 is a qualified alternative within the same family. Verify pinout compatibility with the original design. Ensure that the data rate capabilities meet the system requirements. Check for any differences in thermal performance or power consumption between the variants.
