High Quality USB Interface
This GUSTARD U18 USB digital interface offers a high quality design, ensuring excellent performance and accurate sound reproduction. 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
To generate an extremely accurate clock signal, the U18 uses two Accusilicon AS338 oscillators with a jitter of only 38fs and a Gustard K2 ultra low noise clock synthesizer. Moreover, the power supply of the clocks is done by a LT3045 linear regulator with a noise level of only 0.8µVrms. The power supply stage uses a large custom toroidal transformer, optimized for audio use.
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.
Excellent Performance & Wide Compatibility
For its audio outputs, the Gustard U18 offers Toslink Optical, Coaxial, AES and I2S via HDMI. On this last output, it supports high-resolution audio streams up to PCM 32bit 768kHz and DSD512. Moreover, the I2S pinout is configurable in 4 modes to adapt to most devices on the market. Finally, we note the presence of an MCLK input and WCK output on BNC.
Specifications
- XU216 from XMOS has 16 cores, which brings rich resources and 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 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 isolator . selected crystol for Hi-end audio AS338 :Two AS338 Hi-End audio oscillators from Accusilicon. The jitter is as low as 38fs, whic h greatly improves the bass quality, and bring a more harmony sound.
- Specific toroidal transformer for audio:The power supply of clock is based on LT 3045-a high performance low dropout linear regulator, whose RMS Noise is only 0.8μVRMS (10Hz to 100kHz).
- IIS-H Configurable IIS pinout:Configurable HIS pinout with 4 modes. Stock configuration is Gustard mode Click right to change pinout and long push is to change DSDflag. Please confirm your DAC'S pinout before change this option. Only support these 4 modes.
