Details:
-It adopts ES8620, the latest USB audio interface solution from American ESS, which supports PCM 32bit/768KHz and DSD512 at the highest, and supports DOP and Native DSD at the same time.
-A 128MB SDRAM is used as the system buffer and digital audio processing FIFO.
-Up to 3 FPGA are used to implement the USB audio interface clock management and the external 10M clock part of the audio clock frequency synthesizer, all of which use independent power supply to avoid mutual interference of FPGA internal wiring.
-In the USB audio interface part, an FPGA is used to implement the USB audio interface main control IC to run in Slave mode.
-The audio clock synthesis circuit of the external 10M clock part uses two FPGAs corresponding to the audio master clock frequency synthesizer of 44.1KHz and 48KHz respectively.
-The local audio clock source adopts dual femtosecond clock. This machine uses 2 American ACCUSILICON AS318-B ultra-low phase noise crystal oscillators as the local audio clock source, and the RMS jitter is as low as 88 femtoseconds (10Hz-1MHz)
-Built-in audio dedicated toroidal transformer.

U16 supports 4 types of IIS standard output, which can be switched by long pressing the left button.
