DESCRIPTION
The MCSO2 is a High Frequency SMD Oscillator that incorporates an
integrated HCMOS circuit together with an XTAL. It operates under
vacuum in a hermetically sealed ceramic package.
FEATURES
Outstanding hermetic sealing with gold-tin preform.
High stability and low aging guaranteed by hermetic sealing.
Very fast start-up.
Wide temperature range.
Operates in fundamental mode.
High shock and vibration resistant.
100% Pb-free, RoHS-compliant.
Overall frequency stability over
