DS90UB953TRHBTQ1

Overview

The DS90UB953TRHBTQ1 is a MIPI CSI-2 serializer designed for automotive applications, certified to AEC-Q100 standards. It supports data rates up to 4.16 Gb/s with four LVCMOS inputs and one FPD-Link III output. The device operates on a 1.8 V supply voltage within a range of 1.71 V to 1.89 V, drawing approximately 178 mA. It functions reliably across an extended temperature range from -40°C to +105°C. Housed in a compact 32-VQFN package measuring 5x5 mm, it facilitates high-speed video transmission in demanding environments.

Feature Summary

• Supports MIPI CSI-2 input protocols including YUV422 formats
• Integrates GPIO pins with internal ADC for voltage sensing capabilities
• Includes PLL lock detection mechanisms to maintain stability during temperature variations

Applications

• Automotive camera systems requiring MIPI CSI-2 serialization
• ADAS sensor interfaces utilizing FPD-Link III technology
• In-vehicle infotainment display driver circuits

Procurement Notes

Verify the specific suffix TRHBTQ1 against official Texas Instruments documentation to confirm package type and tape-and-reel specifications. Ensure compliance with AEC-Q100 automotive qualification requirements for your target application environment. Cross-reference datasheet revisions to account for initialization sequence updates regarding temperature ramp-down ranges.

Selection Notes

Select this component when a single-channel serializer is required for MIPI CSI-2 sources. Confirm that the system power budget accommodates the 178 mA operating current at 1.8 V. Verify that the PCB layout supports the 32-VQFN footprint and thermal dissipation needs for operation up to 105°C ambient temperature.

Part Context

This part belongs to the DS90UB953 family of serializers. It serves as the transmitter side in a FPD-Link III link, typically paired with compatible deserializers like the DS90UH9xx series. The Q1 designation indicates automotive-grade reliability and extended temperature performance suitable for vehicle integration.

Replacement Considerations

Direct functional substitutes within the same family include other DS90UB953 variants with different packaging or suffixes. Verify pin compatibility and register settings before swapping. No alternative cross-brand components are officially confirmed as direct replacements.
