Description
LHY Audio OCK-2P is a platinum-grade 10MHz master clock generator with six independently driven sine- and square-wave outputs. Its selected OCXO, isolated thermal chamber, two-stage regulation and selectable grounding target reference digital audio systems that demand the lowest close-in phase noise.
Why it stands out
-115dBc close-in phase noise
The selected OCXO reaches a guaranteed -115dBc at 1Hz offset.
Six flexible clock outputs
Three sine and three square outputs include both 50-ohm and 75-ohm connections.
Thermally controlled clock core
An independent chamber stabilizes the OCXO operating environment.
Upgraded power and grounding
A 30VA transformer, LM350T/LT3041 regulation and float/ground control support system integration.
Best for
- Reference DAC, streamer and transport systems
- Systems clocking several compatible components
- Users needing both 50-ohm and 75-ohm outputs
- Systems requiring sine and square 10MHz signals
Not ideal for
- Equipment without a 10MHz clock input
- Users unsure of required impedance or waveform
- Systems needing 44.1kHz or word-clock output
- Portable or battery-powered setups


EMiUZEK Buying Notes
- Verify every receiving device requires 10MHz and confirm impedance, waveform and accepted level.
- OCK-2P does not carry audio; it supplies a timing reference only.
- Allow at least 15 minutes warm-up and approximately 60 minutes for full thermal stability.
Frequently asked questions
Does it improve every digital device?
Only equipment with a compatible 10MHz clock input can use it.
Can all six outputs operate together?
Yes, the distribution stage is designed for multiple outputs.
Which cable impedance should I use?
Match the receiving device: 50 ohms or 75 ohms.
Does it output sine and square wave?
Yes, three of each.
How long should it warm up?
15 minutes basic, about 60 minutes full.
Can it replace a word clock?
No. It is a 10MHz reference, not an audio word-clock generator.
