(Please notes t he item price includes only the hardware. To compare, the xmos used in our original 384k stereo USB I2S PCB is 500MIPS processing power.Ģ) 4 layer PCB, solid ground plane (a must for high speed digital circuit), low noise linear regulator.ģ) NDK NZ2520SDA Ultra low phase noise oscillator and Murata capacitor sourced from Japan directly (guarantee no fake product from China)Īccording to the official datasheet, the phase noise of NZ2520SDA is much better than the famous crystek 957 under 25khz(human listenable range)įor easier comparsion(lower is better), we overlay the two phase noise graph at the same scale, under 25khz(human listenable range) NZ2520SD(red line) is better, over 25khz(human unlistenable range) crystek 957 is better.Ĥ) If multichannel is not needed, this PCB can work the same as a normal stereo USB audio device with I2S and SPDIF output.ĥ) Extreme diyer can use the onboard full size XSYS connector to program the xmos with their customized firmware to add more feature and function. The wealthy extra processing power and ports enable user to add more customized feature and function without affect the audio quality. PCM 768kHz and DSD1024 can also be supported with external 45.1584Mhz 49.152Mhz clock and customized firmware.ġ) XMOS XCORE-200 XU216-512 with 2 Tiles 16 Cores upto 2000MIPS in dual issue mode.
Maximum 32 channels can be supported if the user flash the XMOS with TDM I2S capable firmware. The default firmware on the DXIO MC(3W) support 6 channels 384 kHz I2S output, 4 channel 384kHz I2S input, spdif output, OLED VU meter and volume up/down control button. Alternative firmware for 192kHz 8 channel in, 8 channel out, spdif output, OLED VU meter and volume up/down control button is also available. Assembly in highend SMT factory, no excess soldering flux on the PCB surface. Higher ESD protection and r uns more stable. *New 2021 DXIO MC 3W version uses dedciated JST-XH 2P socket near the 1V low noise linear regulator for external 3.3V(>1A) regulated power supply. This item includes DXIO MC(3W) USB to/from I2S/DSD SPDIF PCB and a FREE 0.96 OLED display PCB until stock last.
