Here is the second version of SINGXER SU digital interface. It gains more computation power and can now handle digital streams up to 768kHz 32-bit PCM & DSD1024 - namely thanks to the introduction of ultra-high precision Accusilicon clocks.

As any true platform for digital audio connectivity, SINGXER SU-2 significantly expands the scope of your USB  digital sources (PC, streamers, smartphones etc ...) and allows a connection via SPDIF (coax), I2S (LVDS HDMI), or even AES / EBU to your DAC, DSP or FDA.

Its electronic components as well as its architecture (FPGAs with dual clock) allowing it to offer high-performance audio while covering all requirements for a connection within a high-fidelity system.

It also features a complete isolation (150 Mbps isolation chip) to cancel any interference if the source does not already have an isolated USB connector. The isolation chip itself is then corrected by a FPGA circuit in order not to cause additional jitter during the operation.

Input and output for clock signals

To go even further, the SU-2 provides a clock input (10 MHz) on standard 50Ohm socket compatible with most of the TC clock, GPDSO, and even atomic clocks models. In this mode, the SU-2 can also function as a frequency converter (10 MHz to 44.1 - 384kHz).

Reciprocally, the device is able to export its own clock output via a SP/CLK (BNC) connector. It can thus operate in master mode for any device with a clock input. In its autonomous clock mode, the SU-2 in Singxer is capable of generating a clock signal of 44.1 kHz to 384kHz (sample clock) or a signal to 22.5792Mhz 49.152Mhz (master clock). The circuit enables its standalone external clock mode whenever the USB connector is disconnected.
