It uses the latest ARM Cortex-M4 as the core microprocessor as the main control of the USB data part. SU-2 adopts the self-developed chao low-jitter clock system (AS-318B series of ACCUSILICON, ultra-low jitter at femtosecond level), large-capacity FPGA as the core of Digital audio data processing, and has a standard USB2.0 input interface , Rich 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 external 10Mhz clock input, using common 50 ohm input impedance design.\u003cbr\u003e\u003cbr\u003eSU-2 is not only a USB interface, but also can be used as an independent master clock product.\u003cbr\u003e\u003cbr\u003e1. 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)\u003cbr\u003e\u003cbr\u003e2. 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.\u003cbr\u003e\u003cbr\u003eSU-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 high-end interface, mainly using the following three unique technologies:\u003cbr\u003e\u003cbr\u003e1. Full isolation technology (ground isolation), using a 150Mbps full isolation chip, which can completely isolate the interference from the PC;\u003cbr\u003e\u003cbr\u003e2. Source synchronization technology and FPGA shaping technology reshape the isolated I2S signal; thereby eliminating the additive jitter caused by the isolation chip;\u003cbr\u003e\u003cbr\u003e3. The self-developed clock system adopts ACCUSILICON's high-performance crystal oscillator, low phase noise, low jitter; an external 10Mhz clock can also be selected, supporting various atomic clocks, constant temperature crystal oscillators, and GPDSO input.\u003cbr\u003e\u003cbr\u003eThe standard accessory is a USB cable, the default delivery is not equipped with a power cord)\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eBelow is a photo of the chassis:\u003cbr\u003e\u003cbr\u003eTechnical index:\u003cbr\u003e\u003cbr\u003eSampling rate supported by each output interface:\u003cbr\u003e\u003cbr\u003ePCM: 44.1KHz, 48KHz, 88.2KHz, 96KHz,\u003cbr\u003e\u003cbr\u003e176.4KHz, 192KHz, 352.8KHz, 384KHz, 705.6KHz, 768KHz\u003cbr\u003e\u003cbr\u003e[I2S out supports all sampling rates, S\/PDIF supports up to 384KHz, DOP128]\u003cbr\u003e\u003cbr\u003e2.8 MHz (DSD64)-DOP, native\u003cbr\u003e5.6 MHz (DSD128)-DOP, native\u003cbr\u003e11.2 MHz (DSD256)-DOP,native\u003cbr\u003e22.5792 MHz (DSD512)-DOP, native\u003cbr\u003e45.1584 MHz (DSD1024)-native\u003cbr\u003e\u003cbr\u003e[I2S out supports all DSD formats, S\/PDIF and AES\/EBU support DSD128 DOP mode]\u003cbr\u003eBit width: up to 32 bit over I2S output\u003cbr\u003e\u003cbr\u003eUp to 24 bit over S\/PDIF\u003cbr\u003e\u003cbr\u003eElectrical standards for each interface:\u003cbr\u003e\u003cbr\u003e1.

Carry out 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 output performance.\u003cbr\u003e\u003cbr\u003e2. 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.\u003cbr\u003e\u003cbr\u003eI2S interface adopts HDMI socket output:\u003cbr\u003e\u003cbr\u003e1.
