VSMF SERIES: Multi-Frequency Voltage Control Crystal Oscillator with Low Jitter Output
The VSMF clock series is a cutting edge family of High Frequency, Low Jitter Output, Multi-Frequency VCXO
based on an advanced digital PLL platform. The VSMF oscillators are available in a 7x5mm ceramic package
with output frequency from 10MHz to 1.2 GHz. The VSMF units are pre-programmed with up to 2 different output
frequencies, any of which are user selected. Such flexibility significantly reduces design cycle time and overall
cost. The VSMF oscillator design incorporates a low frequency crystal along with low Jitter frequency
synthesizer to provide a wide range of frequencies. The VSMF Clocks are available in LVCMOS, LVPECL and
LVDS outputs, making them suitable for a wide range of applications.
