The SOtM sCLK-OCX10 Master Clock Generator is now available for order.

The sCLK-OCX10 is a master clock generator that produces a high purity 10 MHz clock signal.

SOtM (Soul Of the Music) told us: “Normally a clock signal is an angled square digital signal, but the sCLK-OCX10 is different. It produces a pure analogue sine wave of 10 MHz, and this sinusoidal clock signal is the method applied for the best signal reproduction. This is because of reduced noise compared of the analogue sine wave compared to the angled square digital clock signal. To make this possible, the sCLK-OCX10 consists of only analogue circuitry which contains 10 years of know-how from SOtM”.
