Product introduction:
SU-2 digital interface is a high-performance USB digital audio interface newly developed by our team, using the latest ARM Cortex-M4 as the core microprocessor As the master of the USB data part. SU-2 uses a self-developed ultra-low jitter clock system (AS-318B series of ACCUSILICON, ultra-low jitter up to femtosecond level), a large-capacity FPGA as the processing core of Digital audio data, and a standard USB2.0 input interface , Abundant output interfaces, including XLR balanced output AES, coaxial RCA and BNC, I2S interface with HDMI socket output, complete master clock and word clock (WCLK) output. SU-2 supports an external 10Mhz clock input and adopts a common 50 ohm input impedance design.
SU-2 is not only a USB interface, but also can be used as an independent master clock product.
1: When used as an independent master clock, it can output 44.1K-384K word clock, or output 22.5792Mhz-49.152Mhz master clock. (When the USB is not connected, it will be used as the master clock device by default).
2: When using an external 10Mhz clock input, it can also be used as a frequency converter; support 10Mhz conversion to 44.1K-384K word clock, or output 22.5792Mhz-49.152Mhz master clock.
SU-2 is a brand-new USB interface developed by us to replace the original SU-1; PCM sampling rate is up to PCM 768K, and DSD is up to DSD1024. Using large-scale FPGA as the core of computing processing, we transferred part of the FPGA algorithm technology of the flagship interface SU-6 to SU-2; it is positioned in the mid-to-high-end interface, mainly using the following three unique technologies:
1: Full isolation technology (ground isolation), using a 150Mbps full isolation chip, which can completely isolate the interference from the PC.
2: Source synchronization technology and FPGA shaping technology reshape the isolated I2S signal, thereby eliminating the additive jitter caused by the isolation chip.
3: The self-developed clock system adopts ACCUSILICON''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s high-performance crystal oscillator, low phase noise, low jitter, and can also choose an external 10Mhz clock, supporting various atomic clocks, constant temperature crystal oscillators, and GPDSO inputs.
plan the details:
1: Implement the design concept that electricity is the mother of sound, attach importance to the design of power circuits, and use high-performance, low-noise and fast-response LDO as the main power supply. The whole board uses multiple independent LDO power supplies, and the clock part even uses ADI''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s ultra-low noise LDO, which lays a solid foundation for ensuring the excellent performance of the output.
2: The PCB motherboard adopts a 4-layer circuit board design to ensure a complete ground plane and power layer, and a high-speed digital design method to ensure the signal integrity and power integrity of the entire board. The clock signal is specially processed, and the package design and precise impedance control are adopted to ensure the signal quality of the clock and improve its anti-interference ability. The input and output signals follow the standard design, especially the USB high-speed signal adopts 90 ohm differential impedance control.

System compatibility:
1: Windows 7, Windows 8, Windows 10, 32/64 bit, need to install a special driver
2: Native MacOS 10.6 and later, the system comes with a driver
3: Native Linux with UAC2 compliant kernel, the system comes with a driver,(Tested on Ubuntu and Daphile systems, based on INTEL X86 platform)
4: Android OS 4.2 and above, the device needs to support the OTG function. Generally speaking, the Android 5.0 system is supported by default. The version below 5.0 is recommended to be used with a special player
Electrical standards for each interface:
1: The USB input socket is a standard USB-B type female socket, and the USB power supply range is 4.5V-5.1V
2: RCA interface outputs standard S/PDIF signal, the level is 550mV (connected to standard load), and the output impedance is 75 ohms
3: The power input is 115V/230V AC, and the imported TALEMA transformer is used internally for power supply
I2S interface adopts HDMI socket output:
1: LVDS differential signal with a level of 3.3V
2: DSD ON signal, 5V power supply(Small current), The MUTE signal has been processed by the CPLD inside, and there is no need to output the MUTE signal
3: The DSD ON signal can be defined by itself, and the DSD ON signal can be output to the PIN13, 14, 15, 16 pins of the socket at will
Flexible HDMI-I2S output configuration:
1: Switches 1-4 correspond to PIN13-16 pins of HDMI sockets. Pull it to the ON position, it means that the HDMI PIN has the function of DSD_ON.
2: Switches 5 and 6 are modes for configuring the clock output:
When switch 5 is OFF, the clock outputs MCLK, and when it is ON, the clock outputs WCK
switch 6 configures the output of the SP/CLK interface, output SPDIF signal when OFF, and output WCLK/MCLK signal when ON.
3: Switch 7 can individually set the left and right channels in DSD mode in the I2S signal.
4: Switch 8 can set the line sequence of BCLK in the I2S signal; when it is OFF, PIN4 is BCLK+, PIN6 is BCLK-
5: Switch 9 can set the line sequence of LRCLK in the I2S signal; when it is OFF, PIN7 is LRCLK+, and PIN9 is LRCLK-
6: Switch 10 can set the line sequence of DATA in I2S signal; when OFF, PIN1 is DATA+, PIN3 is DATA-
SU-2 can be configured by SW switch to adapt to different I2S standards.
But as far as we know, the HDMI-I2S of every manufacturer in the world is different. For most manufacturers, HDMI-I2S is a proprietary protocol of the manufacturer. So, I’m sorry, SU-2 can’t adapt to all HDMI-I2S machines, so we don’t accept returns due to the incompatibility of the I2S interface.
However, currently we can give the following HDMI-I2S from different manufacturers. Among the following manufacturers, some of the DACs tested are no problem.
