The SRC4190IDBR is a stereo asynchronous sample-rate converter (ASRC) used to convert audio streams between unrelated clock domains-ideal for systems where source and destination clocks are not synchronous. This makes it common in digital mixing consoles, digital audio workstations, broadcast distribution, and high-end A/V equipment.
SRC4190 integrates high-quality digital filtering with a wide sampling-ratio range and supports typical serial audio data formats including I2S and TDM. In TDM mode it can support daisy-chain style expansion in multi-channel designs (system-level implementation dependent). Control pins enable mode and format configuration for straightforward hardware integration.
The device is supplied in a compact 28-pin SSOP package (SRC4190IDBR) and is suited for professional audio designs that need robust clock-domain bridging without sacrificing noise and distortion performance.
Converts audio between independent clocks, reducing jitter coupling and simplifying system integration between ADC/DSP/transmitter blocks in complex digital-audio pipelines.
Designed for professional/broadcast use with strong dynamic-range and low-distortion characteristics to preserve program material during conversion.
Supports common serial formats such as I2S and TDM, helping SRC4190 fit into many DSP and codec ecosystems without large glue logic overhead.
The SSOP-28 package is space-efficient for dense audio boards and is practical for volume manufacturing and rework.
Supports a wide input-to-output sampling ratio range, enabling conversion between many common audio rates in real systems (implementation depends on clocking and mode settings).
Serial ports support common audio data formats including I2S, Left-Justified, Right-Justified, and TDM (format availability depends on configuration).
Provides control pins for mode/format selection, mute/bypass behaviors and other system integration requirements, suitable for designs with limited MCU overhead.
