This is a high-performance USB digital audio interface, using the XMOS latest xCORE-200 series chips. this board is using self-developed core, low-jitter clock system, clock system used in Japan KDS low phase noise TCXO, frequency accuracy of up 2PPM, RMS JITTER is in 0.5PS less. FUN01 input using a standard USB2.0 interface with rich output interfaces, including XLR balanced output AES, RCA coaxial and optical output, with RJ45 socket output I2S interface. Power input DC 5V.

 After a long period of development and tuning, and ultimately achieve the advanced digital interface level. Its positioning in the high-end interface, mainly uses the following advanced technologies:

1, ground full isolation technology, can interfere with the PC completely from the ground and other front-end equipment, isolation technology uses high-speed chip rate up to 150Mbps;

2, CPLD shaping technology, I2S signal isolation after the re-shaping; thus effectively eliminating the isolation chip to bring added jitter;

3, developed its own system clock, high-performance crystal KDS, and low phase noise and low jitter.

4, using the latest XMOS program: XU208, XU208 is the second generation XMOS chip memory is 2 time of U8.computing speed arrived1000MIPS, U8 is 500MIPS.
