OCK-2P | Platinum Edition — референсный мастер-клок

OCK-2P — генератор опорной частоты 10 МГц на базе OCXO.

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.

В: Чем отличаются OCK-2S и OCK-2P?

О: Оба устройства — мастер-клоки OCXO на 10 МГц. OCK-2P — усовершенствованная версия OCK-2S; отличия приведены ниже.

• A higher-precision OCXO with lower phase noise (< -115 dBc vs. < -110 dBc)
  
• Improved internal circuit and power supply design
  
• Enhanced chassis and internal isolation structure
  

OCK-2P focuses on further refinement in stability, detail, and timing accuracy, while OCK-2S already delivers excellent core performance.

Q: What is the purpose of the Float / Ground switch?

A: If multiple devices are grounded, a ground loop can occur and cause hum or noise. Switching one device to Float breaks the loop and helps reduce or eliminate the noise.
