Product Spotlight: The E8000 OCXO — Ultra-Low Phase Noise Performance

Our flagship E8000 OCXO achieves exceptional close-in phase noise, setting a new benchmark for precision frequency control.

The E8000 OCXO represents the culmination of years of crystal and oscillator design refinement. With phase noise of -175 dBc/Hz at 10 kHz offset (10 MHz), it sets a new standard for commercially available oven-controlled oscillators.

Key Performance Highlights

Achieving this level of phase noise requires careful attention to every aspect of the design:

  • SC-cut resonator with premium low-noise crystal blank
  • Ultra-low-noise oscillator circuit topology
  • High-stability double-oven temperature control
  • Careful PCB layout to minimise vibration sensitivity

Applications

The E8000 is ideal for use as a reference oscillator in test and measurement equipment, radar systems, and telecommunications infrastructure where the lowest possible phase noise is required.
