14 pin DIP OCXO 


Bomar Crystal is able to offer a full line of ultra low tolerance thru hole Oven Controlled Crystal Oscillators. OCXOs are used for applications where frequency tolerance and stability are critical like Satellite Radios, Sonet Clocks, Synthesizers, Instrumentation and GSM Base Stations. Frequency stability to ±50ppb with low phase noise is available.


  • Frequency stability to ±50ppb
  • Frequency range from 2.000 MHz to 100.000 MHz
  • High precision and high reliability
  • Extended temperature of -40o to +75oC. available
  • Available in 3.3Vdc, 5.0Vdc, or 12.0Vdc
  • CMOS or Sine Wave available
  • AT-cut 
  • All Products meet the European Union Initiative (RoHS) for Lead (Pb) free content and requirements for re-flow profiling using lead-free solder.
