1.This USB digital interface Supports DSD and PCM audio. Lossless output of SACD, CD, DXD,
DVD Audio. Supports up to PCM1536K and DSD1024. It is mainly composed of three chips.
USB3300 is responsible for the physical transmission of USB data, STM32F446 (ARM
Cortex-M4 180MHz) is responsible for the main control and audio buffer, and ALTERA
CPLD is responsible for the audio signal output. Absolute physical isolation is formed
between the chips, which do not snatch resources from each other and do not constitute
interference. This is different from the single-chip solution, and is also an important sign
of high-quality digital interfaces. This interface uses the AS318-B crystal from AccuSilicon
for audio with very low phase noise. The typical phase noise is less than 100fs. The CPLD
circuit part has also been redesigned and optimized specifically for the AS318-B crystal, so
that the advantages of this crystal can be fully utilized.

3.This interface also opens configuration mode for advanced players. The MCLK output frequency can be individually configured for any format. From 64Fs to 512FS, from 2.8224MHZ to 49.152MHz, let the DAC chip play excellent performance. You can also write VID and PID and device strings arbitrarily to adapt to any standard USB2.0 audio driver.
The supported formats and sampling rates are as follows: 32-bit PCM (backward compatible with 24 and 16-bit) formats support 44.1KHz, 48KHz, 88.2KHz, 96KHz, 176.4KHz, 192KHz, 352.8KHz, 384KHz, 705.6KHz, 768KHz, 1411.2KHz and 1536KHz sampling rates. The DSD format supports DSD64, DSD128, DSD256, DSD512, and DSD1024, and is transmitted losslessly using DoP (DSD64 ~ 512) or Native (DSD64 ~ 1024) protocols.
4.The supported operating systems are:
Windows XP, Windows Vista, Windows 7, and Windows 8 require the installation of a universal third-party USB Audio 2.0 driver that supports all audio formats and sample rates.
Windows 10 system comes with USB Audio 2.0 driver, which can support DSD format of PCM and DoP protocols. With a universal third-party USB Audio 2.0 driver installed, all audio formats and sample rates are supported.
Mac OS comes with USB Audio 2.0 driver, which can support DSD format of PCM and DoP protocols.
iOS7 and later versions come with USB Audio 2.0 driver, which can support DSD format of PCM and DoP protocols.
Android 5.0 and later versions come with a USB audio 2.0 driver that supports all audio formats and sample rates.
Linux system (when UAC2 kernel driver module is mounted), including Volumio, Moode, Daphile, etc., can support all audio formats and sampling rates
