DS90UA101TRTVJQ1

Overview

The DS90UA101TRTVJQ1 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, including stereo I2S or time-division multiplexed (TDM) formats, accommodating up to eight stereo channels. It functions with an audio system frequency range of 10MHz to 50MHz and requires a single 1.8V power supply. The serial output interface transmits data over a single shielded twisted pair or coaxial cable using embedded clocking, DC equalization, and scrambling techniques.

Feature Summary

• Supports low-latency transmission with delays under 15 microseconds for real-time audio processing.
• Integrates a bidirectional control channel compatible with I2C protocols for device configuration and status monitoring.
• Includes four dedicated general-purpose input/output pins for additional system control flexibility.

Applications

• Automotive information entertainment systems requiring distributed multi-channel audio distribution.
• Active noise cancellation systems utilizing high-speed serial audio links.
• Distributed multi-channel audio architectures in vehicles reducing interconnect complexity.

Procurement Notes

Verify the specific suffix JQ1 to confirm the reel packaging configuration and automotive qualification grade. Ensure compatibility with the corresponding deserializer, such as the DS90UA102-Q1, for complete link functionality. Confirm that the design accounts for the required 1.8V supply voltage and appropriate ESD protection measures per ISO 10605 standards during integration.

Selection Notes

Select this component when designing automotive audio networks requiring serialization of multiple I2S or TDM streams onto a single differential pair or coaxial cable. It is suitable for applications prioritizing reduced wire harness weight and size while maintaining low latency. Ensure the host processor supports the necessary I2C control interface for configuring the serializer settings and managing the bidirectional communication channel effectively.

Part Context

This part belongs to the Texas Instruments FPD-Link family of serializers tailored for automotive digital audio. It complements deserializers like the DS90UA102-Q1 to form a complete point-to-point audio link. The device addresses the need for high-bandwidth audio transmission with minimal pin count and cabling in modern vehicle infotainment and safety-critical audio systems.

Replacement Considerations

Direct pin-compatible replacements within the same series include the DS90UA101TRTVRQ1, which differs primarily in packaging type rather than functional specifications. Verify that any substitute maintains the same AEC-Q100 Grade 2 qualification and thermal performance characteristics for automotive reliability.
