Gustard U18 DDC Digital Interface USB Interface DSD512 PCM768Khz XU216 K2 Fully Isolation AS338 Hi-End Crystol IIS USB Audio Interface (Black)

• GUSTARD U18 USB interface uses the XMOS XU216 solution, which supports DSD512 PCM768K. The chip has 16 cores for more abundant resources to run more easily.
• U18 DDC uses fully isolated technology for ground isolation. The PCB physical isolation design and 200Mbps fully isolated chip are used to isolate the interference from PC.
• U18 uses LPLD digital shaping technology to reshape the IIS signal after isolation to eliminate the additive jitter caused by the isolated chip.
• U18 USB DDC uses second-generation ultra-low noise clock synthesis technology and can be externally connected to a 10M frequency thermostatic clock. the K2 clock module can synthesize the 10M frequency with its extremely low loss into the master clock required for audio.The clock power supply of U18 adopts ultra-low noise regulator LT3045 ultra-low noise LDO with excellent performance. 10Hz~100KHz broadband noise 0.8 uVrms.
• USB DDC U18 uses two of Accusilicon's new AS338 series Hi-End level audio crystal, in order to meet the demanding design requirements, each chip is encapsulated with nitrogen, 100% phase noise meter full QC, its phase noise and short-term stability is far ahead of similar products. The jitter is as low as 38fs, which greatly improves the overall density and stability of the low frequency texture.
