The sCLK-OCX10 is a SOtM’s first master clock device that outputs high-precision clock signals using a very precise and ultra low-noise 10MHz OCXO.

By the user’s choice, the performance of 10MHz clock can be selected as Standard, Advanced or Reference, and the output signal can be selected as 50ohm and 75ohm sine wave.

A device that uses a 10MHz master clock input can achieve a dramatic sound improvement  by the performance of the 10MHz master clock and the sCLK-OCX10 will prove how the good quality of 10MHz master clock should be performed.

* The sCLK-OCX10 is still under development, the specification and the image shown in this page is not the final and could be changed in future. *
