The Singxer SU-6 USB Digital Interface has the XMOS' latest xCORE-200 series and Xilinx's high-performance large-scale PGA chip. It uses a thermostat-level clock system and Crystek's two CCHD-957 femtosecond crystal oscillators to provide a solid foundation for the superior audio signal quality of the SU-6 output. For outputs, it has an S/PDIF for fiber/coaxial RCA and BNC outputs, AES/EBU for XLR balanced output, RJ45, and HDMI interfaces. The power system design is optimized and the audio section is powered by a 7.5F (7.5 million uf) super capacitor.
