OCXO - 50.0 x 50.0 x 19.0mm


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 radar systems, test and measurement equipment, broadcast standards, WiMax/WLAN, and cellular base stations. Frequency stability to ±0.2ppb with low phase noise is available.


  • Frequency stability to ±0.2ppb
  • Frequency range from 10.000 MHz to 20.000 MHz
  • High precision and high reliability
  • Extended temperature of -40o to +70oC. available
  • Available in 5.0Vdc or 12.0Vdc
  • HCMOS or Sine Wave available
  • SC cut 
  • All Products meet the European Union Initiative (RoHS) for Lead (Pb) free content and requirements for re-flow profiling using lead-free solder.
