OCXO Product Family

OCXO – Base Line

AXTAL’s baseline OCXO series is developed for applications requiring high short- and medium-term stability. These products are used as reliable frequency sources in reference clocks, RF chains, and timing infrastructures.

  • ppb-level frequency stability
  • Low phase noise
  • Stable operation over wide temperature ranges
  • Space, military, and industrial product options

OCXO – Ultra-Low Phase Noise Line

This series represents AXTAL’s core area of expertise. It is designed for applications in which phase noise directly limits performance, such as radar, microwave communications, and precision RF systems.

  • Ultra-low phase noise (optimized for radar and RF reference applications)
  • Low vibration sensitivity
  • High short-term stability (Allan deviation)
  • Suitable for test and measurement systems and master clock applications

TCXO Product Family

AXTAL TCXOs are developed for systems requiring stable frequency generation against temperature variations and particularly stand out with low g-sensitivity and low phase noise.

  • Compensation over wide temperature ranges
  • Low mechanical sensitivity
  • Options suitable for space and defense applications
  • CMOS, LVDS, and differential output options

Vibration-Insensitive (Low-G) Oscillators

AXTAL offers specialized oscillator solutions for applications where mechanical vibration and acceleration cause frequency deviation.

  • Radar platforms
  • Mobile military systems
  • Avionics and carrier platforms

These products are designed to minimize the effects of mechanical influences on phase noise and frequency stability.
