Singxer SU02

The SU-2 digital interface is a high-performance USB digital audio interface The microprocessor features the latest ARM Cortex-M4 as the core and is the main control for the USB data exchange. SU-2 uses a custom ultra-low jitter clock system (ACCUSILICON's AS-318B series, which achieves ultra-low jitter at the femtosecond level). A large-capacity FPGA serves as the digital audio data processing core and has a standard USB2.0 input interface. The SU-2 utilizes a diverse output interface, including XLR balanced output AES, coaxial RCA and BNC, I2S interface with HDMI socket output, perfect master clock, and word clock (WCLK) output. SU-2 supports external 10Mhz clock inputs using a common 50 ohm input impedance design. The SU-2 is not only a USB interface, but it can also be used as an independent master clock center. 1. When used as an independent master clock, it can output a word clock of 44.1K-384K, or output a master clock of 22.5792Mhz-49.152Mhz. (When not connected to USB,
