Product outlines
①
Power input connector : Connect to +12Vdc or +9Vdc by the supplied DC power
cable.
②
Power voltage select jumper : Jumper Off when conn12Vdc. Jumper On
when conn9Vdc.
③
Constant voltage output connector : Use when another board needs powers.
Output to about 8.6V when connecting +12Vdc, output to around 7.1V when
conn9Vdc.
④
Frequency control input connector (SEL0) : Use when the frequency control input
is needed.
⑤
Frequency control input connector (SEL1) : Use when the frequency control input
is needed.
⑥
Clock output 1 (U.FL)
⑦
Clock output 2 (U.FL)
⑧
Clock output 3 (U.FL)
⑨
Clock output 4 (U.FL).
⑩
Master clock input connector (MCX) : 75 Ω connector for a master clock input
⑪
Master clock input connector (U.FL) : 50 Ω connector for a master clock input.
⑫
Frequency control select jumper (SEL2, 3) : To use, special order is required.
⑬
+3.3Vdc output connector: It is the output connector of the internal Ultra Low
Noise Regulator. Use when needs +3.3Vdc from another board.
⑭
+5Vdc output connector: It is the output connector of the internal Ultra Low
Noise Regulator. Use when needs +5Vdc from another board.
⑮
Clock connect PCB : Install to the other boards which needed to replace the
clock and connect by the supplied RF cable.
sCLK-EX ordering information
①
A frequency for Clock output 1 (U.FL)
②
A frequency for Clock output 2 (U.FL)
③
A frequency for Clock output 3 (U.FL)
④
A frequency for Clock output 4 (U.FL)
⑤
When adding 50Ω Master clock
⑥
When adding 75Ω Master clock
Precautions
On the back side of the sCLK-EX, each clock output frequency is labeling by the sticker. When connecting RF cable to other
boards, be careful not to misconnect the frequency.
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.
