    Description

    Precision Redefined: The Reference Timing Standard

    The LHY Audio OCK-2P is a professional-grade 10MHz master clock generator engineered to provide the absolute reference frequency for the world's most demanding digital audio systems. By replacing the internal clocks of your DACs, CD players, and network switches with the OCK-2P’s ultra-stable signal, you eliminate the "digital grit" and restore the natural, fluid harmonics of the original recording.

    Why the OCK-2P is Essential:

    • Professional Grade SC-CUT OCXO: The OCK-2P uses a hand-picked, high-specification SC-CUT Oven Controlled Crystal Oscillator. This core provides superior long-term stability and extremely low phase noise, ensuring your digital audio components operate in perfect synchronicity.

    • Triple Independent Outputs: Featuring 3 BNC outputs, the OCK-2P can synchronize three devices at once. Each output is physically isolated to prevent cross-interference.

    • Universal Compatibility: Each of the 3 outputs features its own independent toggle for 50 $\Omega$ / 75 $\Omega$ impedance and Sine Wave / Square Wave selection. This makes it compatible with everything from consumer Hi-Fi to professional studio equipment.

    • Silent Power Foundation: Noise is the enemy of precision. The OCK-2P features a high-performance Talema transformer and a multi-stage LT3042 + PNP linear regulator circuit ($<1\mu V$ noise), ensuring the OCXO operates in a perfectly clean electrical environment.

    • Premium Thermal Management: The heavy CNC aluminum chassis isn't just for shielding; it provides a stable thermal mass to help the internal oven maintain a constant temperature for the crystal, minimizing frequency drift.

    Technical Specifications:

    • Output Frequency: 10.000000MHz

    • Clock Core: Selected SC-CUT OCXO

    OCK-2P is a high-performance external master clock fully upgraded from the acclaimed OCK-2S. Featuring a flagship low-phase-noise OCXO, an independent thermos chamber, an enhanced power supply architecture, and ultra-low additive phase noise clock distribution, OCK-2P significantly improves time-base stability and signal purity. A newly added selectable grounding design further enhances system compatibility and noise management in complex audio setups.

    1. Flagship OCXO with Enhanced Close-In Phase Noise Performance

    OCK-2P employs a carefully selected high-performance OCXO, delivering substantial improvements at critical close-in offsets:

    • –115 dBc @1Hz Offset (Guaranteed)
    • –140 dBc @10Hz Offset (Guaranteed)

    Lower close-in phase noise contributes directly to improved sonic stability, enhanced micro-dynamic resolution, and more accurate spatial reproduction.


    2. Independent Thermos Cabinet for Long-Term Stability

    An independent thermos cabinet provides a stable and controlled thermal environment for the OCXO, minimizing the influence of ambient temperature fluctuations. An integrated OCXO warm-up status LED clearly indicates when optimal operating conditions have been reached.


    3. Enhanced Power Architecture for a Cleaner Foundation

    OCK-2P features a 30VA toroidal transformer paired with a two-stage linear regulation topology (LM350T + LT3041). This architecture reduces power-supply noise, improves PSRR, and provides a stable, low-noise foundation for both the clock core and distribution circuitry.


    4. Ultra-Low Additive Phase Noise Clock Distribution

    The upgraded clock distribution amplifier is designed with ultra-low additive phase noise, ensuring consistent timing accuracy and signal integrity even when driving multiple outputs simultaneously.


    5. Selectable Grounding for System-Level Noise Optimization

    OCK-2P adds a dedicated grounding terminal with a selectable ground switch, allowing operation in either grounded or floating mode. This flexible grounding design enables system-level fine-tuning and helps minimize potential ground loops and unwanted noise coupling

    Clock Core: High-performance OCXO
