DS90UB949ATRGCTQ1

Overview

The DS90UB949ATRGCTQ1 is a serializer manufactured by Texas Instruments, designed for automotive applications under the AEC-Q100 standard. It operates within a temperature range of -40°C to +105°C and utilizes a 64-VQFN package with dimensions of 9x9 mm. The device supports a data rate of 2 Mb/s for reverse channels and accepts HDMI input types. It features six inputs and four outputs, converting signals to FDP and LVDS output types. Power supply requirements include a minimum voltage of 1.045 V and a maximum of 3.465 V. The component is surface-mountable and complies with RoHS3 specifications.

Feature Summary

• Supports HDMI v1.4b input with DisplayPort (DP++) compatibility
• Enables high-speed bidirectional communication via FPD-Link III interface
• Integrates GPIO functionality for remote control and status monitoring
• Includes I2C and SPI interfaces for system configuration

Applications

• Automotive camera systems requiring HDMI to FPD-Link conversion
• In-vehicle infotainment display interfaces
• Surround view monitoring system serializers
• ADAS sensor data transmission links

Procurement Notes

Verify the specific suffix 'A' against the official datasheet to confirm pinout and functional variations compared to non-A variants. Ensure the Q1 designation aligns with automotive reliability standards required for the target application. Cross-reference the 64-VQFN package dimensions with PCB footprint libraries to prevent assembly errors during manufacturing integration.

Selection Notes

Select this model when HDMI source compatibility is required alongside FPD-Link III serialization for automotive environments. Confirm that the six-input configuration meets the signal routing needs of the design. Evaluate the thermal performance within the specified operating temperature range to ensure stable operation in enclosed vehicle compartments without additional cooling measures.

Part Context

This component belongs to the DS90UB949-Q1 family of bridge serializers from Texas Instruments. It is engineered to work in conjunction with compatible deserializers such as the DS90UB940-Q1 or DS90UB948-Q1. The series focuses on reducing cable complexity by integrating video, audio, and control data onto single differential pairs for efficient automotive interconnects.

Replacement Considerations

The DS90UB949TRGCTQ1 serves as a primary alternative within the same product family. Verify if the 'A' suffix indicates specific manufacturing lot or minor functional differences before substitution. Ensure pin-to-pin compatibility and identical electrical characteristics are maintained for direct replacement in existing designs.
