OX-174
Ultra Low Noise
Oven Controlled Crystal Oscillator
OX-174
The OX-174 is a low phase noise, high-stability ovenized crystal oscillator in a 28 x 38 mm package. The oscillator has a noise floor
of -175 dBc/Hz, and typical ADEV below 2E-12 for t=0.1 to 100 s. The OX-174 is a member of the OX-17 oscillator series. Other
oscillators in the series include the OX-170 standard oscillator, OX-171 high stability oscillator, OX-172 optimized for 1588 solutions,
and the OX-175 low phase noise, high frequency oscillator. The Microsemi design team will also help develop custom solutions
where performance optimization is required for specific applications. Please contact the factory for customization options.
