LHY OCK-2P Platinum Edition Reference Master Clock Generator
The OCK-2P is a high-performance external master clock, fully evolved from the acclaimed OCK-2S. It integrates a flagship low-phase-noise OCXO, an isolated and temperature-stabilized thermal chamber, an upgraded ultra-clean power supply architecture, and precision clock distribution with extremely low additive phase noise. These refinements work together to significantly enhance time-base accuracy, jitter suppression, and overall signal purity.
A newly introduced selectable grounding system further improves compatibility and allows finer control of noise behavior across complex, high-end audio setups.

Reference Timing for Advanced Digital Audio Systems
FEATURES
- Designed for high-end digital audio systems requiring precise timing accuracy
- System optimization results may vary depending on system configuration
- OCK-2P is the official upgraded model replacing OCK-2S
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.
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.
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.
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.
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.
Optimal operating conditions indication
An integrated OCXO warm-up status LED visually indicates when the oscillator has reached optimal operating conditions.
Independnt termal OCXO chamber
OCK-2P introduces an independent thermal chamber, providing a more stable and controlled temperature environment for the OCXO.
30 VA Toroidal Transformer
OCK-2P features a Noratel 30 VA transformer, doubling the power headroom compared to the 15 VA design used in OCK-2S. Greater power reserve results in: Improved transient response, Lower supply impedance, Enhanced overall stability
Two-Stage Regulation: LM350T + LT3041
The two-stage linear regulation topology further reduces noise and improves PSRR compared to the single-stage design of the OCK-2S.
This ensures a cleaner and more stable power foundation for both the OCXO and the distribution circuitry.
Ultra-Low Additive Phase Noise Clock Distribution
OCK-2P upgrades its clock distribution amplifier to an ultra-low additive phase noise design, maintaining exceptional signal integrity even with multiple outputs.
