DS90UA101TRTVTQ1

Overview

The DS90UA101TRTVTQ1 is a multi-channel digital audio serializer designed for automotive applications, certified to AEC-Q100 Grade 2 standards. It operates within a temperature range of -40°C to +105°C and utilizes a WQFN-32 package. The device supports flexible digital audio inputs, accommodating up to eight stereo I2S or TDM channels. It transmits data over a single shielded twisted pair or coaxial cable using an embedded clock at frequencies between 10MHz and 50MHz. Key electrical parameters include a single 1.8V power supply, 1.8V or 3.3V I/O interfaces, four dedicated general-purpose input/output pins, and ultra-low latency of less than 15µs.

Feature Summary

• Supports flexible digital audio input formats including stereo I2S and multi-channel TDM
• Transmits high-speed serialized data with embedded clock over a single differential pair or coaxial cable
• Features a bidirectional control channel compatible with I2C for system configuration

Applications

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

Procurement Notes

Verify the specific suffix 'Q1' confirms AEC-Q100 Grade 2 qualification for automotive use. Confirm the 'TV' suffix corresponds to the WQFN-32 package type. Ensure the ordering part number matches the exact pinout and thermal requirements for the target PCB design before finalizing procurement.

Selection Notes

Select this component when designing automotive audio architectures requiring low-latency transmission of multiple I2S or TDM streams. It is suitable for replacing parallel audio buses to reduce wiring complexity. Verify that the host processor supports the required I2S/TDM formats and that the downstream deserializer is compatible with the FPD-Link III protocol.

Part Context

This device belongs to the DS90UA101 series of serializers from Texas Instruments. It is specifically engineered to interface with compatible deserializers in automotive environments. The Q1 designation indicates compliance with automotive reliability standards, distinguishing it from standard industrial grade components.
