Vectron OX-175 Ultra low noise oven controlled crystal oscillator Datasheet

OX-175
Ultra Low Noise
Oven Controlled Crystal Oscillator
OX-175
The OX-175 is a low phase noise, high-frequency ovenized crystal oscillator in a 28 x 38 mm package. The oscillator has a noise
floor of -176dBc/Hz, and typical ADEV below 5E-12 for t=0.1 to 10 s. The OX-175 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-174 low phase noise oscillator. The Vectron design team will also help develop custom solutions where performance
optimization is required for specific applications. Please contact the factory for customization options.
