DS90UB953ATRHBTQ1

Overview

The DS90UB953ATRHBTQ1 is a FPD-Link III serializer manufactured by Texas Instruments, designed for automotive applications with AEC-Q100 qualification. It converts four parallel MIPI CSI-2 input lanes into a single high-speed serial LVDS output stream at a data rate of 4.16 Gb/s. The device operates within a supply voltage range of 1.71 V to 1.89 V, consuming approximately 180 mA of working current. It supports an extended industrial temperature range from -40°C to +125°C and is housed in a 32-pin VQFN package with exposed pad for surface mount installation.

Feature Summary

• Supports MIPI CSI-2 input interface with four parallel lanes
• Provides single-channel FPD-Link III LVDS serial output
• Includes GPIO pins with integrated ADC for voltage sensing capabilities

Applications

• Automotive camera systems requiring MIPI CSI-2 to FPD-Link III conversion
• Advanced driver-assistance systems (ADAS) video transmission links
• In-cabin monitoring and surround view camera interfaces

Procurement Notes

Verify the complete part number including suffixes such as TRHBTQ1 to ensure correct packaging and automotive grade specification. Confirm that the supplier provides official datasheets and quality certificates matching Texas Instruments standards. Check for moisture sensitivity levels and recommended storage conditions prior to assembly to prevent damage during soldering processes.

Selection Notes

Select this component when a single serial link is required to aggregate four MIPI CSI-2 lanes. Ensure the system power supply can maintain stability within the 1.71 V to 1.89 V range, keeping noise below 25 mVpp to avoid PLL lock loss. Verify that the PCB layout accommodates the 32-VQFN package dimensions and thermal requirements for operation up to 125°C.

Part Context

This device belongs to the DS90UB953A series of FPD-Link III serializers. It is specifically engineered for high-bandwidth video transmission in automotive environments. The 'Q1' designation indicates compliance with AEC-Q100 reliability standards for automotive electronics. It pairs with compatible deserializers like the DS90UB960 or DS90UB954 families.

Replacement Considerations

Direct functional substitutes include other members of the DS90UB953 family, such as the DS90UB953TRHBTQ1. Ensure any replacement maintains the same 4-input to 1-output architecture and FPD-Link III compatibility. Verify pinout and register compatibility if migrating between different package variants within the same series.
