XMSRC4392_VC1¶
4-Channel 192KHz ASRC and 768KHz SSRC Audio Sample Rate Converter with Integrated S/PDIF Transceiver and 2-Way I2S Master/Slave Interface
XMSRC4392 is a high-performance four-channel asynchronous audio sample rate converter based on XMOS high-performance chips, designed specifically for professional audio applications. Compared to the SRC4392's dual-channel SRC solution, this product offers double the processing capability while achieving significant optimization in both cost and performance.
- The product integrates two independent SRC modules (SRC_A and SRC_B), each capable of processing two audio channels, supporting ultra-high sampling rates up to 768KHz, providing exceptional flexibility and high-performance audio sample rate conversion for various digital audio systems.
- Supports SSRC sample rate conversion from 44.1KHz to 768KHz, ASRC sample rate conversion from 44.1KHz to 192KHz, and handles 16bit/24bit/32bit audio data processing.
- The product features outstanding audio performance metrics, with THD+N (@1kHz, 0dBFs) ≤ -130dB for both SSRC and ASRC, providing professional-grade audio processing solutions for audio equipment manufacturers.
