sCLK-EX master clock
installation guide
1.
Refer to the sCLK-EX installation guide and install the sCLK-EX accordingly. Depends on what sCLK-EX package use, the different installation guide is
provided.
2.
A U.FL – BNC cable is for 50Ω impedance, a MCX – BNC cable is for 75Ω impedance. Refer to the image below and connect the correct cable
according to the correct impedance of the external master clock input to the sCLK-EX and fasten the BNC connector bracket to the PC case.
3.
The Detect LED turns on once the clock output synchronizes to the external master clock input. The Detect LED located next to the Operate LED and
the Operate LED blinks once the sCLK-EX operates normally.
Precautions
I.
The installation guide is based on sCLK-EX1 tX-USBhubIN combo package. Please refer to how to name sCLK-
EX, sCLK-EX12M5075 means enabled 12Mhz frequency for Clock output 1 and add 50Ω Master Clock Option and 75Ω
Master Clock Option.
I.
The sCLK-EX master clock option offers
- 50Ω Master Clock Option : it comes with 50Ω U.FL to BNC cable.
- 75Ω Master Clock Option it comes with 75Ω MCX to BNC cable.
II.
The standard master clock input frequency is 10MHz. The different input frequency is available, if you need the
different input frequency, you will need to ask in advance of the order.
III.
All sCLK-EX is capable to synchronize an external clock as like 10MHz Master clock if you order the Master clock option.
IV.
The sticker on the back side of the sCLK-EX shouldn’t be torn or damaged because the serial number is essentially
needed if you want to add the master clock options, change the current frequency to the other frequency or enable the
additional clock output to your current sCLK-EX.
