The SMSL G1 locks your digital gear to a single 10 MHz reference so transients are tighter, imaging feels realer, and bass is locked in. An SC-cut OCXO with ±3 ppb accuracy sits under a constant-temperature shield, fed by a low-noise linear supply and four independent buffer stages that drive up to four components at once. Compact, solid, and compatible with CD transports and DACs that accept a 10 MHz input, like SMSL’s own PL200T MQA-CD Transport and PA200 GaN Power Amplifier.\u003cbr\u003e\u003c\/p\u003e\n \u003ch2\u003e\u003cstrong\u003eBring your music in lock step\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp\u003eDigital audio lives and dies by clock accuracy. The G1 provides a single, steady 10 MHz reference to your DAC, transport, and other digital gear so they agree on when “now” is. Less nanosecond-level jitter means crisper imaging, fewer smeared transients, and low frequencies that stop and start when they should. \u003cbr\u003e\u003c\/p\u003e\n \u003ch2\u003e\n \u003cstrong\u003eSC-cut OCXO for long-term stability\u003c\/strong\u003e\u003cbr\u003e\n \u003c\/h2\u003e\n \u003cp\u003eAt the center is an SC-cut oven-controlled crystal oscillator (OCXO) with phase noise measured at −105 dBc\/Hz at 1 Hz offset and frequency accuracy within ±3 ppb. In plain terms: drift is tiny and noise is low. It reaches basic thermal stability in about two minutes, and it settles further after roughly ten minutes.\u003cbr\u003e\u003c\/p\u003e\n \u003ch2\u003e\n \u003cstrong\u003econstant-temperature shield, calmer phase noise\u003c\/strong\u003e\u003cbr\u003e\n \u003c\/h2\u003e\n \u003cp\u003eThe OCXO sits inside a dedicated, insulated chamber that evens out micro-temperature swings and blocks external heat sources. Stable temperature equals stable frequency, and it’s one of the simplest ways to keep phase noise down and microdetail intact.\u003cbr\u003e\u003c\/p\u003e\n \u003ch2\u003e\n \u003cstrong\u003efour 10 MHz outputs with independent buffers\u003c\/strong\u003e\u003cbr\u003e\n \u003c\/h2\u003e\n \u003cp\u003eOne clock, four destinations. Each BNC output is driven by its own buffer to hold output impedance steady and handle real-world loads without sag. Run a transport and a DAC in parallel, add a DDC or streamer, and keep everything on the same timeline. Outputs are 3.3 Vpp square wave with selectable 50\/75 Ω loading to match the gear on the other end.\u003cbr\u003e\u003c\/p\u003e\n \u003ch2\u003e\n \u003cstrong\u003elow-noise power with room to experiment\u003c\/strong\u003e\u003cbr\u003e\n \u003c\/h2\u003e\n \u003cp\u003eA toroidal linear supply and multi-stage LDO regulation create a quiet 6 µVrms power environment for the oscillator and output stages. Prefer to bring your own supply? A rear DC input accepts 9–15 V, giving tinkerers a clean path to try a favorite linear power supply. \u003cbr\u003e\u003c\/p\u003e\n \u003ch2\u003e\n \u003cstrong\u003ecompact, milled aluminum chassis\u003c\/strong\u003e\u003cbr\u003e\n \u003c\/h2\u003e\n \u003cp\u003eA CNC-machined unibody keeps resonance down and looks tidy on the rack.
