OCXO

OCXO is a crystal oscillator that uses a constant temperature bath to keep the temperature of quartz crystal constant and minimizes the change of oscillator output frequency caused by the change of ambient temperature.

Key Features

  • Ultra-high stability, wide temperature, low phase noise, low consumption, small size, support customer product.

Applications

  • Wire communication
  • Wireless communication
  • Private power network
  • Industrial control
  • Instruments etc.
