Overview
The X72 rubidium (Rb) oscillator is the newest and smallest of Symmetricom’s
family of precision frequency generator components. This fifth generation Rb
oscillator reflects significant advances in physics miniaturization and integration and
offers a low height (0.70 inch / 17.7 mm), a small footprint, and an industrial
temperature range of –40° C to +85° C.

Drawing on over 30 years of experience, the X72 design has been refined for low
cost mass production and can be easily integrated into time, frequency and
synchronization systems, requiring only one input supply voltage. It can be mounted
directly onto a circuit board as a component of a module used in 0.8 inch wide card
slots. It offers the high reliability and accuracy of a rubidium oscillator in a new
design concept benefiting from the many years of experience Symmetricom has
gained in fielding tens of thousands of rubidium oscillators.
