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 high frequency 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.
