XMSRC4194_VC1¶
4-Channel 192KHz ASRC Audio Sample Rate Converter with 2x S/PDIF and 2x I2S Interfaces and TDM Cascade Mode
XMSRC4194 is a high-performance 4-channel asynchronous sample rate converter based on XMOS chip architecture. This product is fully compatible with the core functional specifications of SRC4194, including 16:1 to 1:16 wide-range sample rate conversion, 144dB dynamic range, and comprehensive support for multiple digital audio formats such as I2S, Left-justified, Right-justified, and TDM.
- Compared to SRC4194, the core advantage of XMSRC4194 is the integration of two additional S/PDIF input interfaces, providing users with more flexible signal source selection. Users can flexibly switch between I2S input and S/PDIF input according to application requirements, significantly enhancing system connectivity and adaptability.
- The XMOS chip architecture ensures high reliability and excellent audio processing performance, providing professional audio equipment manufacturers with a more competitive solution choice.
- Dual SRC module architecture, with each module processing 2 audio channels, capable of independent operation, supporting a total of 4-channel audio sample rate conversion simultaneously.
