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

Built-in CPLD pre-shaping technology, FPGA-based source synchronization technology re-shaping the isolated I2S signal, thus eliminating the additive jitter caused by the isolation chip.
The newly designed FPGA algorithm, built-in FIFO buffers the data and then outputs, SPDIF output is re-encoded by FPGA, so that the coaxial output can support PCM 384K and DSD DOP128 at the highest.

Using CRYSTEK's CCHD-957 high-performance femtosecond crystal oscillator, with the self-developed constant temperature system and ultra-low noise super capacitor power supply system, further improve the short-stability performance of the clock.
Original single clock system, all circuits of the whole machine adopt synchronous clock design, in which USB clock is synthesized by PLL derived from femtosecond clock.

The SU-6 digital interface is a new generation of high-performance USB digital audio interface. It uses XMOS' latest xCORE-200 series and Xilinx's high-performance large-scale PGA chip. The SU-6 is a digital interface using a thermostat-level clock system. Crystek's two CCHD-957 femtosecond crystal oscillators provide a solid foundation for the superior audio signal quality of the SU-6 output. The SU-6 digital interface uses a standard USB2.0 input interface, while the SU-6 has a rich output interface, including S/PDI for fiber/coaxial RCA and BNC outputs, AES/EBU for XLR balanced output, RJ45 and HDMI interfaces. Output I2S (including DSD ON signal), clock output supports MCLK main clock and WCLK word clock. The power system design was optimized and the audio section was powered by a 7.5F (7.5 million uf) supercapacitor.

SU-6 is newly developed USB interface, which is positioned at the high-end interface. Compared with previous products, we mainly use the following four new self-developed technologies:
1, built-in CPLD pre-shaping technology, FPGA-based source synchronization technology re-shaping the isolated I2S signal, thus eliminating the additive jitter caused by the isolation chip.
2, the newly designed FPGA algorithm, built-in FIFO buffers the data and then outputs, SPDIF output is re-encoded by FPGA, so that the coaxial output can support PCM 384K and DSD DOP128 at the highest.
3, using CRYSTEK's CCHD-957 high-performance femtosecond crystal oscillator, with the self-developed constant temperature system and ultra-low noise super capacitor power supply system, further improve the short-stability performance of the clock.
4. Original single clock system, all circuits of the whole machine adopt synchronous clock design, in which USB clock is synthesized by PLL derived from femtosecond clock.

DESIGN DETAILS

1. Implement the design concept of electric power as the mother of sound, pay attention to the design of power circuit, adopt external DC input, built-in super capacitor power supply, with high performance, low noise and fast response LDO. The whole board is powered by up to 6 independent LDOs. The digital audio board is powered by a secondary LDO. The clock part even uses LT's ultra-low noise LDO, which lays a solid foundation for ensuring the ultimate performance of the output.
2, in order to ensure excellent electrical transmission performance, XLR sockets are made of Swiss Neutrik products, USB-B sockets are made of TE, and enthusiast BNC and RCA coaxial sockets are made for Taiwanese manufacturers. Even the fuses are selected from the United States. Litteluse model.
3. The audio board is designed with a 4-layer board to ensure a complete ground plane and power plane. High-speed digital design is used to ensure signal integrity and power integrity of the board. Special processing of the clock signal, using packet design and accurate impedance control, to ensure the signal quality of the clock and improve its anti-interference ability.
4, input and output signals are in accordance with the standard design, especially the USB high-speed signal uses 90 ohm impedance control, also built-in anti-static TVS protection circuit; I2S signal uses LVDS differential level standard, impedance control is 100 ohms, 4 outputs are used A separate LVDS driver.
