Giwnhvx USB Digital Interface Pcm1536 DSD1024 Compatible with Amanero Italy XMOS to I2S

It is mainly composed of three chips, USB3300 is responsible for the physical transmission of USB data, STM32F446 (ARM - 180MHz) is responsible for main control and audio buffering, and ALTERA CPLD is responsible for audio signal output. The chips form absolute physical isolation, do not grab resources from each other, and do not constitute interference. This is different from a single-chip solution, and it is also an important sign of a high-quality digital interface. You can modify its configuration parameters through the configuration tool software. You first find a win7 computer and install the configuration mode driver. If you use win10, you must turn off the mandatory signature mechanism before installing. The method is written in the documentation. This USB digital interface is independently developed by Digital Audio Technology Group and has completely intellectual property rights. Support DSD and PCM audio. Lossless output SACD, CD, DXD, DVD Audio. Supports up to PCM1536K and DSD1024. Then open the configuration tool. and hold the button on the interface without letting go, plug in the USB, and then release the button. At this time, the interface enters the configuration mode. Create a new configuration first, then modify the configuration, then write the configuration, and finally disconnect. Plug and unplug the USB cable again to return to playback mode. This interface uses a 2520 small package ultra-low phase noise audio dedicated crystal oscillator, and the image noise is as low as -158dBc/Hz @100kHz. The CPLD circuit part has also been redesigned, and the clock generation part has been specially optimized, so that the advantages of delicate and transparent can be fully utilized.
