This USB to ElectroTos translator makes it possible to use the new ElectroTos interface and all its advantages with existing USB audio sources (PC, laptop, streamer). It is bus powered by the USB audio source, so no external power supply is required. Power supply filters inside the translator clean up the USB bus power supply to obtain clean supply voltages for the translator circuits. The USB translator supports both, standard S/PDIF and low jitter ElectroTos protocols. It can be used with existing DACs (S/PDIF protocol) or our new Fractal DAC (ElectroTos low jitter protocol). The USB translator is based on the popular XMOS XU208 processor and asynchronous feedback. This enables the use of local, low jitter system (24 MHz) and audio clocks (22.5792MHz and 24.576 MHz). Special synchroniser / driver circuit ensures that the output jitter does not exceed audio clock jitter. ElectroTos completely insulates the PC / streamer from the DAC, eliminating ground loop noise and wired LAN related sound quality degradation. The USB translator supports 44.1/16 ... 192/24 (full S/PDIF range) and is UAC2 compliant (no drivers required).
