SRC4192IDBG4

Audio Special Purpose Overview

The SRC4192IDBG4 is a stereo asynchronous sample-rate converter from the Burr-Brown (Texas Instruments) family, designed for high-performance digital audio applications. It supports input-to-output sampling ratios ranging from 16:1 to 1:16 and handles sampling rates up to 192 kHz. The device features a dynamic range of 144 dB and total harmonic distortion plus noise (THD+N) of -140 dB. It operates from a single 3.3-V analog supply with a digital I/O supply range of 1.65 V to 3.6 V. The component includes flexible serial ports supporting I2S, Left-Justified, Right-Justified, and TDM formats, along with high-performance linear-phase digital filtering.

Audio Special Purpose Feature Summary

• Automatic sensing of input-to-output sampling ratios ranging from 16:1 to 1:16
• High-fidelity performance with 144 dB dynamic range and -140 dB THD+N
• Flexible audio interfaces supporting I2S, Left/Right Justified, and TDM modes
• Supports sampling rates up to 192 kHz
• Low group delay option for interpolation filters and direct downsampling capability

Audio Special Purpose Applications

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

Audio Special Purpose Procurement Notes

Verify the manufacturer designation as Texas Instruments (TI), which acquired the Burr-Brown product line. Confirm the package type is SSOP-28 (DB package) and the operating temperature range covers -40°C to 85°C (Industrial grade). Ensure the specific suffix 'G4' corresponds to RoHS compliance and tube packaging if required by the bill of materials.

Audio Special Purpose Selection Notes

Select the SRC4192IDBG4 when hardware control via mode pins is preferred over software configuration. Unlike the SRC4193, this variant lacks an SPI port and internal control registers, relying instead on fixed logic inputs for format and mode selection. It is suitable for designs requiring pin-compatible replacement for the AD1896.

Audio Special Purpose Part Context

This component belongs to the SRC419x family of 192-kHz stereo asynchronous sample-rate converters. It is functionally similar to the SRC4193 but differs in its control interface; the SRC4192 uses dedicated control pins rather than an SPI port. Both devices share the same 28-pin SSOP package and core audio processing capabilities.
