DS90UA102TRHSJQ1

Overview

The DS90UA102TRHSJQ1 is a dual-channel digital audio serializer manufactured by Texas Instruments, designed for automotive applications. It operates within the DS90UA10x series and complies with AEC-Q100 Grade 1 standards, supporting a temperature range of -40°C to +105°C. The device features two serial links capable of transmitting multi-channel I2S or TDM audio data over a single shielded twisted pair or coaxial cable using embedded clock technology. It utilizes a 32-pin WQFN package and requires a single 1.8V power supply.

Feature Summary

• Supports dual-channel transmission of multi-channel digital audio formats including I2S and TDM
• Integrates a bidirectional control channel for low-speed communication alongside high-speed data
• Provides flexible I/O options with configurable general-purpose input/output pins

Applications

• Automotive active noise cancellation systems
• Distributed multi-channel audio architectures in vehicles
• In-vehicle infotainment system interconnects

Procurement Notes

Verify the specific suffix 'TRHSJQ1' against official Texas Instruments documentation to confirm package type and qualification grade. Ensure compatibility with the corresponding deserializer, such as the DS90UA101, for proper link establishment. Confirm moisture sensitivity levels and reflow soldering profiles prior to assembly.

Selection Notes

Select this component when a dual-link solution is required for distributing digital audio across multiple zones in an automotive environment. Compare against single-channel alternatives if bandwidth requirements are lower. Verify that the target application supports the necessary I2C control interface for configuration and monitoring.

Part Context

This part belongs to the FPD-Link III family of serializers, which are engineered to reduce wiring complexity in automotive designs. It complements deserializers like the DS90UB914A to create complete video and audio transmission paths. The Q1 suffix indicates automotive qualification, ensuring reliability under harsh operating conditions typical of modern vehicle electronics.

Replacement Considerations

Direct functional substitutes within the same family include the DS90UA101TRHSJQ1 for single-channel applications. For dual-channel requirements, verify pin-to-pin compatibility with other members of the DS90UA10x series before implementation.
