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.

Application Notes:  
None  
Notes:  
1. Unless otherwise stated, all values are valid after warm-up time and refer to typical conditions for supply voltage, frequency  
control voltage, load, and temperature (25°C).  
2. Retrace is defined as the frequency difference between the end of two 24 hour on power periods with a 24 hour off period in  
between while at a constant temperature.  
3. Not all options and codes available at all frequencies.
