DS90UB971RHBTQ1

Overview

The DS90UB971RHBTQ1 is an automotive-grade serializer within the FPD-Link IV family, manufactured by Texas Instruments. It converts MIPI CSI-2 input signals into high-speed FPD-Link IV and LVDS outputs for transmission over coaxial or shielded twisted pair cables. The device supports a data rate of 7.55 Gb/s per lane. It operates on a single 1.8 V supply voltage and functions reliably across an extended temperature range from -40°C to +115°C. The component is housed in a compact 32-pin VQFN package with exposed pad, designed for surface-mount installation.

Feature Summary

• Supports MIPI CSI-2 input interface for direct connection to image sensors
• Transmits data via FPD-Link IV and LVDS output protocols
• Includes integrated CDR (Clock Data Recovery) circuitry
• Complies with AEC-Q100 Grade 2 automotive reliability standards

Applications

• Automotive advanced driver assistance systems (ADAS)
• Surround view camera systems
• In-cabin monitoring applications
• Digital rearview mirror systems

Procurement Notes

Verify the complete part number including suffixes such as RHBTQ1 to ensure correct packaging, temperature grade, and moisture sensitivity level. Confirm that the supplier provides original manufacturer documentation or traceability records. Check for RoHS compliance status and specific shipping restrictions related to humidity sensitivity class prior to ordering.

Selection Notes

Select this serializer when interfacing MIPI CSI-2 cameras with FPD-Link IV deserializers in automotive environments requiring operation up to 115°C. Ensure system design accommodates the 1.8 V power domain and VQFN-32 thermal dissipation requirements. Verify compatibility with downstream deserializer models supporting the same line rate and protocol specifications.

Part Context

This component belongs to the DS90UB971 series of FPD-Link IV serializers. It is specifically engineered for high-bandwidth video transmission in vehicles. The 'Q1' designation indicates automotive qualification, while 'RHBT' specifies the 32-pin VQFN package and tape-and-reel delivery format. It pairs typically with compatible deserializers like the DS90UB9702-Q1.

Replacement Considerations

Direct functional replacements within the same family include other DS90UB971 variants with differing suffixes for package or reel options. Cross-family migration to FPD-Link III devices requires significant redesign due to protocol differences.
