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.
