Technical features

  1. Latest XMOS, xCORE - 200 series for USB digital interface which doubles in processing MIPS  achieving 1000 MIPS  as compared to the old XMOS chip that was commonly used. 
  2. Unique High-speed isolation design to complete isolating the noise between PC and SU-1. It adopted a special circuit design, using high-speed CPLD/FPGA for digital audio signal reconstruction. 
  3. SU-1 uses two expensive audio -level low jitters clocks (Femtosecond clock) CCHD - 575 from Crystek.
  4. Five independent power supplies for all major digital parts, including ADI ultra low noise regulator driving the Crystek CCHD clock.
  5. Four-layer high speed digital PCB design with impedance matched and separate ground plane and power supply layer.
