SRC4192IDBRG4

Audio Special Purpose Overview

The SRC4192IDBRG4 is a stereo asynchronous sample-rate converter (ASRC) from Texas Instruments, housed in a 28-pin SSOP package. It supports input and output sampling rates up to 212 kHz with an automatic sensing range of 16:1 to 1:16. The device delivers a dynamic range of 144 dB and a total harmonic distortion plus noise (THD+N) of –140 dB. It operates on a single 3.3-V supply (VDD) with a digital I/O supply (VIO) ranging from 1.65 V to 3.6 V. Key features include high-performance linear-phase digital filtering, jitter attenuation, and flexible serial port support for I2S, Left-Justified, Right-Justified, and TDM formats.

Audio Special Purpose Feature Summary

• Automatic sensing of input-to-output sampling ratios from 16:1 to 1:16
• Ultra-low distortion performance with THD+N of –140 dB and dynamic range of 144 dB
• Flexible audio interfaces supporting I2S, Left/Right Justified, and TDM modes
• Standalone configuration via hardware control pins for mode, data format, and mute

Audio Special Purpose Applications

• Digital mixing consoles
• Digital audio workstations
• Broadcast studio equipment
• High-end A/V receivers

Audio Special Purpose Procurement Notes

Verify the G4 suffix indicates RoHS compliance and general manufacturing standards as per Texas Instruments documentation. Confirm the IDBRG4 designation corresponds to the SSOP-28 package and reel packaging format. Ensure the component meets the specified operating temperature range of -40°C to +85°C for the intended application environment.

Audio Special Purpose Selection Notes

Select the SRC4192IDBRG4 when hardware-controlled configuration is preferred over software programming. This standalone device differs from the SRC4193, which utilizes an SPI interface for register control. Ensure the design accommodates the 28-pin SSOP footprint and provides separate VDD (3.3 V) and VIO (1.65 V–3.6 V) power rails to meet electrical specifications.

Audio Special Purpose Part Context

The SRC4192 belongs to the SRC419x family of 192-kHz stereo asynchronous sample-rate converters. It is pin-compatible with the AD1896, facilitating direct replacement in existing designs. The device is part of Texas Instruments' professional audio IC portfolio, designed to bridge various digital audio sources and destinations with minimal signal degradation.

Audio Special Purpose Replacement Considerations

The SRC4192 is pin-compatible with the AD1896. For functional upgrades requiring software control, the SRC4193 serves as a compatible alternative within the same package.
