So the full name of it is: LHY OCK-1 fever audio 10Mhz SC cut OCXO ultra low phase noise constant temperature clock ultra femtosecond crystal oscillator... balabalabala
Just reading this sentence is already making a headache for me haha

Anyway, since I sold my interface and my new DAC doesn't have a clock slot, I think it might be a better option to sell it, rather than keep it collecting dust
And here are some specs of it:
Model: ock-1

Output frequency: 10MHz

Output port: 3

Output accuracy: < ± 300ppb

Frequency stability: < ± 50ppb

Output amplitude: ≥ 7dBm @ 50rz

Output waveform: regular wave and square wave

Output impedance: 50 Ω

Near end corresponding noise @ 1Hz (typ): - 110dbc

AC power supply: AC 115 / 230V
Power consumption of the whole machine: < 15W

Size: L270*W130*H65 MM

Weight: roughly 2.5kg
