Pre-order: expected ship date to be announced
A master clock for the Eversolo system: a 10 MHz SC-cut OCXO feeding four independently buffered BNC outputs, for the T10, DAC-Z10, DAC-R8 and any source with an external clock input.
The Eversolo C10 is a high-precision master clock. One C10 feeds up to four components from a single reference, such as Eversolo's T10 streaming transport, DAC-Z10 and DAC-R8, or any source with an external clock input.
What is inside?
A custom 10 MHz OCXO (oven-controlled crystal oscillator) built on an SC-cut crystal, a doubly rotated cut that is less sensitive to temperature change and internal stress. It warms up within five minutes at 25 °C, leaves the factory within ±0.01 ppm, drifts less than 0.003 ppm from −20 °C to +60 °C and ages less than 0.002 ppm per day.
How low is the phase noise?
≤ −115 dBc/Hz at 1 Hz, ≤ −129 dBc/Hz at 10 Hz, ≤ −139 dBc/Hz at 100 Hz and ≤ −145 dBc/Hz at 1 kHz, with a noise floor of ≤ −170 dBc/Hz. Short-term stability is below 9E-13 over one second.
What can I connect?
Four independently buffered BNC clock outputs at 50 ohms, all driven by the same clock source. They run at 10, 25 or 100 MHz, or at word-clock frequencies for the 44.1 kHz family (11.2896, 22.5792, 45.1584 MHz) and the 48 kHz family (12.288, 24.576, 49.152 MHz). An SMB 1PPS input takes an external time reference; every C10 is factory-calibrated for 1PPS timing.
Display and size
An 8.8-inch IPS touchscreen shows warm-up, oscillator temperature, operating status and 1PPS calibration in real time. The aluminum-alloy chassis matches Eversolo's full-width components and measures 365 × 310 × 88 mm with feet; it weighs 5.85 kg.
