GUSTARD U18 USB Interface Fully Isolation K2 Ultra Low Noise Clock Synthesizer DSD512 PCM768kHz XU216
Descriptions:
U18 is the new generation of high-performance USB audio interface designed by Gustard.
XU216 from XMOS has 16 cores, which brings rich resources and a smooth experience.
Fully isolation
Complete grounding isolation is achieved by 200 Mbps isolator to eliminate all interference from your PC
2nd generation clock Synthesizer with ultra-Low noise.
Support external oCxO.
K2 can generate the audio-specific frequency using a 10Mhz clock source with extremely low loss.
Independent CPLO for signal shaping
In the CPLD for signal processing, the isolated IIS signal is reshaped to remove the jitter introduced by the isolator
Selected crystal for Hi-end audio, AS338
Two AS338 Hi-End audio oscillators from Accusilicon.
In order to meet the strict requirements, each crystal is packaged with nitrogen gas, and 100% checked by a phase noise analyzer.
Its phase noise and short-term stability are far ahead of similar products.
The jitter is as low as 38fs, which greatly improves the bass quality, and brings a more natural sound.
The power supply of clock is based on LT3045-a high-performance low dropout linear regulator, whose RMS Noise is only 0.8uVRMS (10Hz to 100kHz).
