輸出GND絕緣/外殼GND選擇功能

• 可以在“與外殼GND隔離”或“外殼GND”之間切換輸出GND電位。如果本機輸出的GND共同接地，則當連接多個設備時，每個設備的GND電位差會流過連接電纜的GND，這會產生稱為GND環路的噪聲。
• 因此，通常最好將每個輸出的GND與噪聲輸出隔離。根據所使用的系統，每個設備的GND可能已正確接地。如果每個設備之間沒有這樣的GND電位差，則將輸出GND接地到機箱GND可能會獲得更好的噪聲效果。
• 由於音頻系統的環境各不相同，因此您可以根據自己的環境選擇最合適的方法。本機的底板配有外殼GND端子。

外部LPS電源

• 本設備設計為只能使用外部直流電源進行操作。確保准備外部直流電源。我們建議使用我們的專用電源（LTPW01P），但是如果規格匹配，您可以使用自己喜歡的線性電源。
• 外部DC規格為13.5V至16V 1A。推薦電壓為15V。 LT3045甚至可以在輸入和輸出電壓之間相差1V的情況下很好地消除噪聲。規格內的輸入/輸出電壓差越小，LT3045的性能就會越好。因此，它可以在13.5V的電壓下工作，以獲得良好的無噪聲直流電源。
• 外部DC插頭標準為2.1mm / 5.5mm。也可以使用普通的DC插頭

終極等級選擇值

• 產品中安裝的OCXO可長時間校準工業設備中使用的產品，並使用特性良好的設備。為了最佳地選擇音頻時鐘，我們全面評估可以進一步檢查的相位噪聲特性和短期穩定性（艾倫色散）

MA系列OP等級選擇值

• 本產品中安裝的OCXO使用已校準幾個月的穩定OCXO單元。為了進行音頻時鐘的最佳選擇，我們正在對相位噪聲特性和短期穩定性（艾倫色散）進行全面評估，以便進行更詳細的檢查。
• 無法僅通過測量內置OCXO單元的輸出特性來評估產品。我們校準的測量值不是直接由OCXO單元輸出的，而是從本產品的輸出端子測量的，以便評估包括緩衝電路在內的所有性能。

選擇基準值 
相位噪聲：偏移1 Hz時為-119至-113 dBc / Hz或更低（OP區分）偏移10 Hz時為-137 dBc / Hz或更低（共）

艾倫方差短期穩定性參考值
[MA-OP19] TAU = 1sec 3.0E-13或更小（0.00030ppb / s）
[MA-OP18] TAU = 1sec 3.4E-13或更短（0.00034ppb / s）
[MA-OP17] TAU = 1sec 3.8E-13或更短（0.00038ppb / s）
[MA-OP16] TAU = 1sec 4.2E-13以下（0.00042ppb / s）
[MA-OP15] TAU = 1sec 4.6E-13或更短（0.00046ppb / s）

Features

• The product uses the new OCXO Type4, and through long-term calibration to select and install equipment with excellent stability.
• The OCXO unit adds a rugged heat insulation box made of heat insulation panels to maintain the environment where OCXO performance is maximized.
• The bottom of the case is made of 2 mm thick aluminum material + 8.4 mm thick laminated iron material. There are a total of 10.4 mm thick plates with a strong vibration control structure. In addition, a laminated magnetic material with a thickness of 5.2 mm is used to construct a strong magnetic shield around the board.
• Using aluminum die-casting three-point support feet, it can be stable on any installation surface. Peak insulators can be replaced with 4 mm screws.
• The output can be set to 50Ω or 75Ω impedance. (Registration utility model)
• You can set whether the output GND potential is connected to the host GND or isolated (insulated). It can respond well to different complex GND processing of each audio system (registered utility model).
• The DC provided by an external DC power supply adjusts the LT3045 with ultra-low noise and ultra-high PSRR inside the unit in a three-cell structure. The cleanest DC is provided to OCXO.
• For the internal board, a 70 μm copper foil board twice the thickness of the ordinary board is used. The internal layout has been verified many times and is in the best state.
• Equipped with an LED monitor, it allows the oven circuit to operate normally and manage the temperature of the OCXO unit.
• Use highly calibrated measuring instruments to strictly measure characteristics. Clock quality is guaranteed by plotting the phase noise and Allen variance at the output of each unit.
• It has a two-year free repair warranty.

Output GND insulation / shell GND selection function

• The output GND potential can be switched between "Isolated from the housing GND" or "Shell GND". If the GND output from this unit is grounded together, when multiple devices are connected, the GND potential difference of each device will flow through the GND of the connecting cable, which will cause noise called GND loop.
• Therefore, it is usually best to isolate the GND of each output from the noise output. Depending on the system used, the GND of each device may be properly grounded. If there is no such GND potential difference between each device, grounding the output GND to the chassis GND may obtain better noise effects.
• Since the environment of the audio system is different, you can choose the most suitable method according to your environment. The bottom plate of this machine is equipped with the GND terminal of the shell.

External LPS power supply

• This device is designed to operate only with external DC power. Make sure to prepare an external DC power supply. We recommend using our dedicated power supply (LTPW01P), but if the specifications match, you can use your favorite linear power supply.
• The external DC specification is 13.5V to 16V 1A. The recommended voltage is 15V. The LT3045 can eliminate noise even when the input and output voltages differ by 1V. The smaller the input / output voltage difference within the specifications, the better the performance of the LT3045. Therefore, it can work at a voltage of 13.5V to obtain a good noise-free DC power supply.
• The external DC plug standard is 2.1mm / 5.5mm. Or you can use ordinary DC plug

Ultimate OP level selection value
The OCXO installed in the product can calibrate the products used in industrial equipment for a long time, and use equipment with good characteristics. In order to optimally select the audio clock, we comprehensively evaluate the phase noise characteristics and short-term stability (Allen dispersion) that can be further checked
OP selection value of MA series

The OCXO installed in this product uses a stable OCXO unit that has been calibrated for several months. In order to make the best choice of audio clock, we are conducting a comprehensive evaluation of phase noise characteristics and short-term stability (Allen dispersion) for a more detailed inspection.
It is impossible to evaluate the product only by measuring the output characteristics of the built-in OCXO unit. The measured value of our calibration is not directly output by the OCXO unit, but measured from the output terminal of this product, in order to evaluate all performance including the buffer circuit.

Choose a base value
Phase noise: -119 to -113 dBc / Hz or lower at 1 Hz offset (OP distinction) -137 dBc / Hz or lower at 10 Hz offset (total)

Allan variance short-term stability reference value
[MA-OP19] TAU = 1sec 3.0E-13 or less (0.00030ppb / s)
[MA-OP18] TAU = 1sec 3.4E-13 or shorter (0.00034ppb / s)
[MA-OP17] TAU = 1sec 3.8E-13 or less (0.00038ppb / s)
[MA-OP16] TAU = 1sec 4.2E-13 or less (0.00042ppb / s)
[MA-OP15] TAU = 1sec 4.6E-13 or shorter (0.00046ppb / s)
[MA-OP14] TAU = 1sec 5.1E-13 or shorter (0.00051ppb / s)
[MA-OP13] TAU = 1sec 5.6E-13 or shorter (0.00056ppb / s)

The above values ​​are not standard catalog values ​​(typical values), but guaranteed values, which are measured separately, so the product quality is constant. There is no so-called "decay".
