Precautions when ordering :
This product is a model for external DC power supply only.
You must have an external DC power supply that meets the specifications of this product.
Our recommended external DC power supply product is "LTPW02" or "LTPW05".
"LTPW02" and "LTPW05" does not include DC cable and AC cable.
Please purchase them as an option.
If you are already using LTPW02 (P) or LTPW05 in your OCXO product, you can supply power from the second DC output terminal of LTPW02 (P). In that case, please purchase only our dedicated DC cable additionaly.
Alternatively, you can use the DC terminal branch plug that comes with this product to distribute the power from the DC terminal supplied to the OCXO to the DC input of this product using a separately sold DC cable.
If you prepare your own external DC power supply, use a linear power supply of 14V-16V 0.2A (or higher).
We will ship your order approximately 12 days after your order is confirmed.
Product Overview :
This is a signal splitter that can divide all OCXO grade high precision 10MHz signals, including our OP21A, into three parts without sacrificing the characteristics.
Equipped with 3 output systems that can be used when multiple clock signals are required in a device configuration such as a single DAC or HUB. Each output system can be set to 50 ohm or 75 ohm impedance. (Utility model registered)
The clock input can be switched between GND grounding and isolation according to the device used for input. (The optimal selection method is explained in detail in the manual) Input impedance is only 50 ohms.
The GND of each output is isolated to eliminate the influence of GND loop noise between devices connected to the output.
Due to its small size, it can be connected directly to the output terminal of the clock body using a BNC relay plug. This connection method allows installation to eliminate signal degradation on the input side as much as possible. (BNC relay plug sold separately)
External DC power supply only. It can be connected to the free DC output connector of our external power supply LTPW01/05. Alternatively, the DC supplied to the OCXO can be distributed and connected using the included DC branch plug. (DC cable sold separately)
DC supplied from an external DC power supply is regulated to a clean 12V by the internal LT3045 and supplied to the circuit.
Comes with a 2-year free repair warranty.
It is a signal distributor that can distribute all of our OCXO grade high precision 10MHz signals into 4 with almost no loss of characteristics.
Equipped with 4 system outputs that can be used when multiple clock signals are required in a device configuration such as a single DAC or HUB. Impedance of 50 ohms or 75 ohms can be set for each output system. (Registered utility model)
You can set whether to connect the output GND potential to the main unit GND or to isolate it. It can handle complicated GND processing that differs depending on your audio system in detail. (Registered utility model)
The input signal conforms to all levels output from all our clock products. The input impedance is only 50 ohms.
The output gain can be selected from 0 dB (voltage ratio 1 times) or + 4 dB (voltage ratio 1.58 times).
The DC supplied from the external DC power supply is regulated to a clean 12V by the internal LT3045 and supplied to the circuit.
Uses aluminum die-cast 3-point support feet that can be stable on any installation surface. It is possible for the user to replace it with a spike support foot, etc. by himself with a 4 mm screw.
Be sure to prepare an external DC power supply as it is exclusively for an external DC power supply. It can be connected from the free DC output connector of our external power supply LTPW01. (DC cable sold separately)
It comes with a 2-year free repair warranty.
About the output impedance 50Ω / 75Ω switching function :
The impedance of the external 10MHz clock input of audio equipment is divided into 50Ω or 75Ω products. In measuring equipment, 50Ω is common, but in audio equipment, the input impedance of the word clock is 75Ω, so the external 10MHz input is also 75Ω in many cases. Impedance matching is effective in preventing the generation of reflected waves, so it is best to match the impedance of the external clock input of your audio equipment.
For our clock products, the clock output impedance can be set to 75Ω / 50Ω according to the device you are using with a switch. (Registered utility model)
Even if your audio equipment changes in the future, impedance matching of the external 10MHz clock can be reliably supported.
Output GND chassis isolated :
For most audio systems, better results are obtained if the GND of each clock output is isolated. By insulating the GND of each CH output, we prevent the effects of ground loop noise caused by the difference in case potential between devices connected to the distributor.
How to connect with OCXO equipment :
