DS90UB953ATRHBRQ1

Overview

The DS90UB953ATRHBRQ1 is a FPD-Link III serializer designed for automotive applications, certified to AEC-Q100 standards. It accepts four MIPI CSI-2 inputs and serializes them into a single high-speed LVDS output channel operating at up to 4.16 Gb/s. The device supports camera resolutions up to 2.3MP at 60fps. It operates within a supply voltage range of 1.71 V to 1.89 V, with a typical operating voltage of 1.8 V. The component functions reliably across an extended industrial temperature range from -40°C to +125°C. It is housed in a 32-pin VQFN package with exposed pad for surface mount installation.

Feature Summary

• Supports MIPI CSI-2 interface for high-resolution camera sensor integration
• Serializes multiple parallel data lanes into a single differential LVDS link
• Includes integrated GPIOs for remote control and status monitoring

Applications

• Automotive surround view camera systems
• Forward-facing collision avoidance cameras
• Radar and sensor signal processing interfaces

Procurement Notes

Verify the complete part number including suffixes to ensure correct packaging and temperature grade. Confirm AEC-Q100 qualification requirements match the target automotive application. Check datasheet revisions for initialization updates regarding PLL lock stability during temperature changes. Ensure power supply noise remains below specified limits to prevent video artifacts.

Selection Notes

Select this serializer when interfacing MIPI CSI-2 sensors to FPD-Link III deserializers over long cable runs. Consider the 4.16 Gb/s bandwidth limit relative to the sensor resolution and frame rate requirements. Evaluate the 32-VQFN package constraints for PCB layout and thermal management. Verify compatibility with downstream deserializer models such as the DS90UB954 or TDES954 series.

Part Context

This component belongs to the DS90UB953A family of FPD-Link III serializers. It serves as the transmitter side of the link, converting parallel camera data into a serialized differential signal. It is commonly paired with compatible deserializers to form complete video transmission chains in advanced driver assistance systems (ADAS).

Replacement Considerations

The DS90UB953TRHBTQ1 is a related variant within the same family. Verify pinout and electrical specifications before substitution. Ensure the replacement matches the required automotive qualification and operating temperature range.
