This meticulous isolation ensures a pristine audio signal devoid of any unwanted disturbances.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e2nd Generation Clock Synthesizer with Ultra-Low Noise: \u003c\/strong\u003eThe U18 employs two Accusilicon AS338 oscillators and a Gustard K2 ultra-low noise clock synthesizer to generate an incredibly accurate clock signal. With a mere 38fs of jitter, and powered by an LT3045 linear regulator with a minimal 0.8µVrms noise level, the clock synthesis is a testament to precision.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eIndependent CPLO for Signal Shaping:\u003c\/strong\u003e In the CPLD for signal processing, the isolated IIS signal undergoes meticulous reshaping, effectively eliminating jitter introduced by the isolator. This ensures that the audio signal remains clean and true to the source.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eExcellent Performance \u0026amp; Wide Compatibility:\u003c\/strong\u003e The Gustard U18 offers a variety of audio outputs, including Toslink Optical, Coaxial, AES, and I2S via HDMI. The I2S pinout is configurable in four modes to adapt to various devices on the market. Supporting high-resolution audio streams up to PCM 32bit 768kHz and DSD512, it caters to audiophiles with diverse preferences.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCrystal Clarity with AS338: \u003c\/strong\u003eThe heart of the U18 lies in its two AS338 Hi-End audio oscillators from Accusilicon. These crystals, packaged with nitrogen gas and rigorously tested, boast a phase noise as low as 38fs, significantly enhancing bass quality for a more natural sound. The power supply of the clock is meticulously regulated by the LT3045, a high-performance linear regulator, ensuring a minimal RMS Noise of only 0.8uVRMS.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eInputs: 1x USB-B\u003cbr\u003e 1x BNC 10MCLK (50Ω,
