LHY AUDIO OCK-2 10MHz Reference Clock 6 Output Interfaces SC-Cut High-Precision OCXO for Audio

Description:
Clock is the heart of digital audio. By providing devices with high-precision clocks, digital audio devices can achieve sound quality with high resolution and transparency, minimizing sampling errors in DACs.
 
All digital audio equipment, including network players, must rely on the clock for digital/to-analog conversion, so the quality of the clock is closely related to the sound quality. The master clock with very low adjacent phase noise is the key to low time base error, and OCK-2 provides a better external clock performance, compared with general built-in clocks.

The OCXO used in OCK-2 has very low phase noise. The phase noise of the rubidium oscillator generally used to measuring instrument is about -70dBc, while the phase noise of the American rubidium oscillator used by most audio manufacturers is about -100dBc, and the phase noise of the OCK-2 OCXO is as low as < -115 dBc at 1Hz! This phase noise is very low.

The back of this device can connect to 6 devices supporting 10M input, including USB DAC network player and SA-CD player. Each output channel has a DIP switch to switch between 50Ω/75Ω. Since the DIP switches are internal, you need to contact customer service for the setting in advance. The default setting is 6CH 50Ω.

Each set of OCK-2 circuits is isolated from the power section output to the buffer driver of the stage. This prevents cross-interference and flickering when multiple devices are connected to the BNC interface. By adding a buffer driver to each circuit, the signal waveform is also less attenuated when all six sets of generated clock signals are shared. Therefore, each BNC interface output can provide an ultra-high accuracy 10MHz clock signal.

Powered by a linear power supply, it has near-zero noise. EMI filtering, 15W UK transformer (for Talema) and high-speed rectifier filtering help maximize the power of super OCXO. Three independent LT3042 and PNP architectures provide UV-level power to the crystal oscillator, frequency modulation reference circuit, and motherboard output. This greatly facilitates critical clock generation and high-precision output.

Features:
- OCK-2 OCXO clock generator with ultra-high accuracy
- Independent 6CH output: 3-way sine wave + 3-way square wave
- Imported SC-CUT OCXO
- Phase noise: < -115 dBc at 1Hz
- Powered by a uV-class linear supply
- A total of 6 outputs. Each output has a DIP switch to switch 50Ω/75Ω (Default setting is 6CH 50Ω)
- Each output interface can be independently switched to ground/isolation
- Monolithic aluminum alloy shell separates the circuits with different functions to reduce interference and mechanical resonance
- Support six 10MHz clock input devices, including USB DAC network player and SA-CD player, which can be connected in parallel
- Each set of circuit of the OCK-2 (from the output of the power section to the buffer driver of the stage) is designed to prevent cross-interference and flicker when multiple devices are connected to its BNC interface
- By adding a buffer driver to each circuit, the signal waveform is also less attenuated when all six sets of generated clock signals are shared. Therefore, each BNC interface output can provide an ultra-high accuracy 10MHz clock signal
- Low jitter: SC-cut OCXO outperforms traditional SPXO femtosecond crystal oscillator. Whether you use a CD player, a digital turntable, or a decoder, clock has a decisive positive effect on the sound system, because it can reflect more detail, realism and more realistic instrument performance
- Imported, high-precision SC-CUT OCXO: The phase noise of the thermostatic crystal oscillator is as low as <-115DBC at 1HZ
- 3CH independent LT3042 and PNP architectures provide uV power to the OCXO, motherboard and FM reference circuit separately. Its noise is close to zero, which helps generate key clock and high-precision output
- EMI filtering, 15W transformer for TALEMA, and high-speed rectifier filtering maximize the performance of OCXO
- With good compatibility, low jitter, and stable transmission, it can make your 10M input device get a more stable and accurate signal. It can also help your device to achieve high resolution and transparent sound quality
- OCK-2 adopts aluminum alloy monolithic hollowed-out shell, separates circuits with different functions to reduce interference and mechanical resonance, and block vibration and external noise
