DS90UA101TRTVRQ1

Overview

The DS90UA101TRTVRQ1 is an automotive-grade multi-channel digital audio serializer designed for FPD-Link III systems. It supports up to eight stereo I2S or TDM audio inputs and features four dedicated general-purpose input/output pins. The device transmits data over a single shielded twisted pair or coaxial cable using embedded clocking, achieving low latency of less than 15 microseconds. It operates within a temperature range of -40°C to +105°C and complies with AEC-Q100 Grade 2 standards. Power is supplied via a single 1.8V source with compatible 1.8V or 3.3V I/O interfaces.

Feature Summary

• Supports flexible digital audio input formats including stereo I2S and multi-channel TDM
• Enables bidirectional control channel communication alongside high-speed forward data transmission
• Integrates DC equalization and scrambling for reliable signal integrity over long cables
• Provides low-latency performance suitable for real-time audio processing applications

Applications

• Automotive information entertainment systems
• Active noise cancellation systems
• Distributed multi-channel audio architectures

Procurement Notes

Verify the component against official Texas Instruments datasheets to confirm authenticity and revision status. Ensure the ordering suffix matches the required package and temperature grade specifications. Cross-reference part numbers with authorized distributors to avoid counterfeit risks. Confirm that the specific variant meets all functional requirements for the intended automotive application before finalizing procurement decisions.

Selection Notes

Select this serializer when designing systems requiring multiple synchronized audio channels over a single interconnect. It pairs effectively with compatible FPD-Link III deserializers like the DS90UA102-Q1. Consider its low latency and robust EMC characteristics for sensitive cabin environments. Verify power supply constraints align with the single 1.8V requirement and check I/O voltage compatibility for system integration.

Part Context

This component belongs to the DS90UA101 series of automotive serializers. It is specifically engineered for FPD-Link III technology, focusing on high-fidelity audio distribution in vehicles. The device simplifies wiring harness complexity by consolidating audio and control signals onto a single differential pair or coaxial line, reducing overall system weight and installation effort.

Replacement Considerations

Consult official substitution guides for direct equivalents. Verify pinout and electrical parameter compatibility before replacing existing designs with alternative serializers from the same family or different manufacturers.
