Singxer SU-6 USB Digital Interface XMOS XU208 CPLD Femtosecond Clock Large

The SU-6 digital interface is a new generation of high-performance USB digital audio interface developed by the Singxer team. It adopts the latest xCORE-200 series from XMOS and Xilinx's high-performance large-scale PGA chip. The SU-6 adopts a digital interface with a constant temperature clock system, and Crystal's two CCHD-957 femtosecond crystal oscillators lay a solid foundation for SU-6 to output high-quality audio signal quality. The SU-6 digital interface adopts the standard USB 2.0 input interface, and the SU-6 has rich output interfaces, including S/PDI for fiber/coaxial RCA and BNC output, AES/EBU for XLR balanced output, I2S (including DSD ON signal) for RJ45 and HDMI interface output, and clock output supporting MCLK master clock and WCLK word clock. The design of the power system has been optimized, and the audio part is powered by a 7.5F (7.5 million uf) supercapacitor.
SU-6 is our newly developed next-generation USB interface, positioned at the high-end interface. Compared to our previous products, it mainly adopts the following four new independently developed technologies:
