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 "LTPW01/02/03/04/05/06".
"LTPW01/02/05" does not include DC cable and AC cable.
Please purchase them as an option.
If you are already using LTPWxx in your OCXO product, you can supply power from the second DC output terminal of LTPWxx. 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-17V 0.2A (or higher).
We will ship your order approximately 15 days after your order is confirmed.
Features :
This is a signal splitter that can divide all OCXO grade high precision 10MHz signals, including our OP23AS, 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 allows you to switch between 75ohm and 50ohm impedance and set GND to ISOLATE/CHASSIS, depending on the connected device and cable.
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 LTPW01/02/05. Alternatively, the DC supplied to the OCXO can be distributed and connected using the included DC branch plug. (DC cable sold separately)
The DC power from an external DC power supply is regulated to a very clean 12V by the built-in LT3045 x 3 parallel circuitry and supplied to the circuit.
Comes with a 2-year free repair warranty.
Changes from previous models:
- Input impedance switching between 50 ohms and 75 ohms
- Internal power supply circuit: LT3045x1 → LT3045x3 in parallel
- High purity achieved by adopting an L network in the impedance matching circuit when outputting at 75 ohms
- Adoption of an isolation transformer to improve output isolation
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.
