STZ-SC Seamless Switcher

　　The STZ-SC Seamless Switcher achieves automatic and manual seamless switching of multiple input frequency signals through measurement and taming methods. Any fault or loss of input signals will not affect the phase continuity of the output signal, making it suitable for fields with high requirements for the continuity of time and frequency signals, such as atomic clock arrays and primary/backup time-frequency systems.

Product features

Supports mixed inputs of 5MHz and 10MHz, with outputs of 5/10MHz

Frequency stability better than 5E-13/s

Phase noise of 10MHz output is <-110dBc/Hz at 1Hz offset

Phase change before and after switching is ≤0.3ns

Suitable for clock arrays, primary/backup systems, and other fields that require high continuity of timing signals.
