This high quality USB to I2S interface module allows you to get an I2S/DSD output from a USB computer source. Associated with a DAC with I2S input, it allows you to create a complete product that can be read from a PC, Mac or Linux source. It works with an ARM Cortex M3 ATSAM3U processor and processes the signals using a XILINX CPLD model XC2C64A. These use two low phase noise TCXO clocks 24.5760 & 22.5792Mhz. This allows the module to interface high sample rates (up to 384Khz / DSD512) with low jitter.
