The SRC4382IPFBR is designed for digital audio products that must accept, process, and transmit audio streams across different clock domains. By using asynchronous sample rate conversion, it decouples the input and output clocks, which helps improve system robustness when sources vary in clock quality or sampling rate.
In a typical signal chain, SRC4382 sits between the digital audio input (e.g., AES3/S/PDIF receiver path) and the downstream audio processing/DAC stage. Its integrated DIR + DIT blocks also simplify digital audio I/O implementation by reducing external glue logic.
The IPFBR ordering is supplied in a lead-free 48-pin TQFP package, commonly used in professional audio interfaces, digital mixers, routers, and broadcast equipment.
Asynchronous conversion allows stable audio streaming even when input and output clocks differ, reducing system sensitivity to source clock variations.
Combines digital audio receiver and transmitter functions with SRC in one device, simplifying audio routing designs and reducing BOM.
Designed for professional/broadcast use-cases where long-term stability, format handling, and predictable behavior matter more than minimal-cost consumer-only solutions.
Pin and register compatibility with TI SRC4392 / DIX4192 family helps with platform reuse and maintenance across product generations.
Two-channel asynchronous sample rate conversion suitable for stereo or dual-channel processing paths.
Integrated DIR/DIT blocks support common digital audio transport use-cases and reduce external interface ICs.
Register-based configuration via serial host interface allows controlled routing, status reporting, and interrupt/error flag handling in complex systems.
