Italian-based Northstar Design is one of the first to offer true 32bit asynchronous USB high speed connectivity. Its USB dac32 has a full range of inputs including USB, coaxial, toslink, AES/EBU, and i2S (S/PDIF are handled up to 24-but 192kHz). Custom USB drivers for PC and MAC os X allows bit perfect transfers between the computer and the DAC. This incoming data are redirected to a FIFO memory and re-clocked with a high precision clock then to an asynchronous sample rate converter (Cirrus CSB421 chip) which upsamples all signal to 192kHz/32-bit. The digital section is completed by a pair of TI Burr-brown PCM 1795 converters in balanced mono configuration. There are two separate power supplies; one dedicated to the digital section and one dedicated to the analog section.
