Key Features
- Asynchronous stereo sample rate conversion up to 192kHz supports mixed-clock audio systems without a common reference clock
- Accepts 16-bit to 24-bit input word lengths with transparent audio quality and ultra-low jitter output for professional audio chains
- Compatible with a wide range of input-to-output sample rate ratios enabling seamless interfacing between 44.1kHz, 48kHz, 96kHz, and 192kHz audio domains
Applications
SRC4190IDB-P is used in professional and consumer audio equipment where audio streams from different clock domains must be bridged without audible artefacts, such as digital mixing consoles, broadcast audio interfaces, and A/V receivers. It also serves in digital audio workstations, studio monitor controllers, and high-end soundcards requiring transparent sample rate conversion between 44.1kHz, 48kHz, 96kHz, and 192kHz standards.

Frequently Asked Questions
What is the maximum sample rate SRC4190IDB-P can convert and what input word lengths does it accept?
SRC4190IDB-P supports asynchronous stereo sample rate conversion at output rates up to 192kHz and accepts input word lengths ranging from 16-bit to 24-bit. This flexibility allows it to interface high-resolution audio sources such as 24-bit/96kHz ADCs or professional digital mixers with systems running at 44.1kHz or 48kHz without requiring sample-synchronised clocks.
In which audio system scenarios does SRC4190IDB-P provide a clear advantage over a synchronous sample rate converter?
SRC4190IDB-P is specifically designed for asynchronous operation, meaning it can accept an input audio stream with an independent clock and produce a 192kHz output locked to a separate master clock. This is critical in broadcast and live audio environments where equipment from different manufacturers—with different crystal oscillators—must exchange 24-bit digital audio without clock locking, avoiding the phase-lock delays and dropouts of synchronous approaches.
What procurement lead time and package should engineers expect when ordering SRC4190IDB-P for a production audio design?
SRC4190IDB-P is available in a small-outline SSOP-28 package, which fits standard SMT assembly processes with a compact board footprint. Engineers designing stereo 192kHz conversion stages should verify current stock levels and lead times with authorised Texas Instruments distributors, as audio-grade ICs can carry 8- to 14-week factory lead times during supply-constrained periods.
