SRC4190IDBRQ1

Audio Special Purpose Overview

The SRC4190IDBRQ1 is an automotive-grade audio sample rate converter (SRC) from Texas Instruments, designed for digital audio interfacing. It supports asynchronous sampling rate conversion up to 192 kHz. The device operates within a supply voltage range of 3 V to 3.6 V and functions reliably across an extended temperature range of -40°C to +85°C. Packaged in a 28-pin SSOP format, it is AEC-Q100 qualified for automotive applications.

Audio Special Purpose Feature Summary

• AEC-Q100 qualified for automotive reliability standards
• Supports asynchronous sampling rate conversion up to 192 kHz
• Operates on a single 3 V to 3.6 V power supply

Audio Special Purpose Applications

• Automotive infotainment systems
• Digital audio signal processing interfaces
• Vehicle audio network synchronization

Audio Special Purpose Procurement Notes

Verify the specific suffix 'Q1' confirms AEC-Q100 automotive qualification status. Ensure the SSOP-28 package matches the target PCB footprint. Confirm that the 3 V to 3.6 V operating voltage aligns with the system power design. Check for RoHS compliance documentation as required by project specifications.

Audio Special Purpose Selection Notes

Select this component when automotive certification is mandatory for audio SRC applications. It is suitable for designs requiring support for high-frequency audio signals up to 192 kHz. Consider the SSOP-28 package constraints for space-limited automotive boards. Verify compatibility with existing digital audio interfaces before integration.

Audio Special Purpose Part Context

This part belongs to the SRC4190 family of audio sample rate converters. The Q1 suffix specifically denotes its qualification for automotive environments under AEC-Q100 standards. It serves as a specialized solution for converting digital audio streams between different clock domains in vehicle systems.

Audio Special Purpose Replacement Considerations

The SRC4190IDBR is the commercial grade equivalent without automotive qualification. The SRC4190IDBRG4 represents a lead-free variant of the commercial version. Direct substitution requires verifying if automotive AEC-Q100 certification is strictly necessary for the application.
